This chemistry video tutorial provides a basic introduction into reaction mechanisms within a chemical kinetics setting. It explains how to write the rate law expression for a reaction mechanism. A reaction mechanism consist of a series of elementary steps or elementary reactions whose rate law can be written from its molecularity - that is from the coefficients of the balanced reaction. The rate of a reaction mechanism is completely dependent on the slow step or the rate-determining step. This video explains how to substitute an intermediate when writing rate law expressions. It contains plenty of examples and practice problems.

Chemical Kinetics Made Easy: Rate Laws for Elementry Reactions Episode #10 Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864, Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating the law of mass action, which states that the speed of a chemical reaction is proportional to the quantity of the reacting substances. Van 't Hoff studied chemical dynamics and published in 1884 his famous "Etudes de dynamique chimique". In 1901 he was awarded by the first Nobel Prize in Chemistry "in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions". After van 't Hoff, chemical kinetics deals with the experimental determination of reaction rates from which rate laws and rate constants are derived. Relatively simple rate laws exist for zero order reactions (for which reaction rates are independent of concentration), first order reactions, and second order reactions, and can be derived for others. Elementary reactions follow the law of mass action, but the rate law of stepwise reactions has to be derived by combining the rate laws of the various elementary steps, and can become rather complex. In consecutive reactions, the rate-determining step often determines the kinetics. In consecutive first order reactions, a steady state approximation can simplify the rate law. The activation energy for a reaction is experimentally determined through the Arrhenius equation and the Eyring equation. The main factors that influence the reaction rate include: the physical state of the reactants, the concentrations of the reactants, the temperature at which the reaction occurs, and whether or not any catalysts are present in the reaction. Gorban and Yablonsky have suggested that the history of chemical dynamics can be divided into three eras. The first is the van 't Hoff wave searching for the general laws of chemical reactions and relating kinetics to thermodynamics. The second may be called the Semenov--Hinshelwood wave with emphasis on reaction mechanisms, especially for chain reactions. The third is associated with Aris and the detailed mathematical description of chemical reaction networks.

In this video we want to discuss the relationship between the kinetics rate equation and reaction mechanism. The reaction mechanism is the detailed breakdown of the overall reaction showing each elementary step that is taking place in that reaction. One of these elementary steps is the slowest step and it determines the rate of the overall reaction. Therefore the slow step is also referred to as the rate determining step. The rate determining step is directly related to the rate equation, where the order of reaction with respect to a reactant is the number of that reactant involved in the slow step. Take for instance the following rate equation where order with respect to A and B is 1 and 2 respectively. This means that in the slow step, 1 A and 2 B are involved hence we can write out the slow step as follows: Example 1 Let's try to write out the rate equation given the mechanism as shown: From the slow step there is 1 X and 1 Y as reactants. Therefore order with respect to X and Y are both 1 and the rate equation can be written as follows: rate = k[X][Y] Example 2 Let's have another example: From the slow step there is 1 AB and 1 B as reactants. Therefore order with respect to AB and B are both 1. The rate equation can first be expressed as: rate = k[AB][B] However AB is an intermediate since it is formed in the first step but removed in the second step. Therefore we need to rewrite the intermediate AB in terms of the reactants that forms AB in step 1. Since AB is formed from 1 A and 1 B, we can write it as first order with respect to both A and B. The rate equation will now look like this: rate = k[A][B][B] = k[A][B]^2 So we can conclude the order of reaction with respect to A is 1 and with respect to B is 2. For the detailed step-by-step discussion on the relationship between rate equation and reaction mechanism, check out this video!

In this video we want to discuss the concept of Pseudo first order reaction in Kinetics. Let's take a look at an example: Given a reaction is first order with respect to both reactants A and B. For an experiment, where [A] = 0.01 moldm-3 and [B] = 0.50 moldm-3, the half life was determined to be 10 minutes. What is the new half life when the concentration of B is changed to 1.00 moldm-3? 1. Determine rate equation Let's first write down the rate equation based on the order of the reaction with respect to A and B. Since order is 1 with respect to both reactants then the rate equation is given as: rate = k [A][B] The overall order of the reaction is 2, which makes it difficult for us to determine half life as we know that half life is not constant for overall order 2 reaction. In fact, in A Level Chemistry syllabus we are only required to find half life for first order reactions. This means that the question is hinting to us that in order for us to determine half life for a second order reaction, we need to change this reaction into a first order reaction. That's where the concept of pseudo first order reaction comes in. 2. Criteria for Pseudo First Order Reaction Once we suspect the question is about pseudo first order reaction we can verify this by looking out for one of these criteria: a. excess reactant - the concentration of excess reactant is treated as constant since the change in the amount of excess reactant is negligible as the reaction proceeds. b. catalyst - the concentration of catalyst is constant as it is chemically unchanged at the end of the reaction. For this question we notice that the concentration of B is 50 times more than concentration of A. So we can treat the concentration of B as constant and make it part of rate constant k. So what we have effectively done is to change an overall order 2 reaction and make it appear like an order 1 reaction. Hence the name pseudo first order reaction. 3. Determine Half Life Since now the reaction is first order, half life is a constant and we can write it in terms of the original rate constant k and concentration of B. From the expression we know that half life is inversely proportionate to concentration of B. Comparing the 2 experiments, when we double the concentration of B from 0.5 moldm-3 to 1.0 moldm-3, we will expect the half life to be halved from 10 minutes to 5 minutes.

This chemistry video tutorial provides a basic introduction into elementary reactions and elementary rate laws. It explains the difference between unimolecular, bimolecular, and Termolecular reactions. An elementary reaction is one in which the rate law can be written from the coefficients of the balanced chemical equation and agrees with empirical data. A unimolecular reaction is a reaction that can proceed using a single molecule. A bimolecular reaction is one in which two molecules must collide in order to react. Termolecular reactions require the collision of three molecules.

This Aakash iTutor video talks about the rate Laws of chemical reactions. The teacher explains the method of determining the rate law of an elementary reaction by taking a look at the stoichiometric coefficient. The order of a reaction can also be predicted on the basis of Rate Laws. Moving on, Complex Reactions are reactions which take more than one step to complete. Writing the rate law for a complex reaction involves analyzing the step wise mechanism of the reaction. The slower step is the rate determining step, and it is used to write the rate law for the complex reaction.

Chemical Kinetics Made Easy: Integrated Rate Law First Order Reactions Episode #05 Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864, Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating the law of mass action, which states that the speed of a chemical reaction is proportional to the quantity of the reacting substances. Van 't Hoff studied chemical dynamics and published in 1884 his famous "Etudes de dynamique chimique". In 1901 he was awarded by the first Nobel Prize in Chemistry "in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions". After van 't Hoff, chemical kinetics deals with the experimental determination of reaction rates from which rate laws and rate constants are derived. Relatively simple rate laws exist for zero order reactions (for which reaction rates are independent of concentration), first order reactions, and second order reactions, and can be derived for others. Elementary reactions follow the law of mass action, but the rate law of stepwise reactions has to be derived by combining the rate laws of the various elementary steps, and can become rather complex. In consecutive reactions, the rate-determining step often determines the kinetics. In consecutive first order reactions, a steady state approximation can simplify the rate law. The activation energy for a reaction is experimentally determined through the Arrhenius equation and the Eyring equation. The main factors that influence the reaction rate include: the physical state of the reactants, the concentrations of the reactants, the temperature at which the reaction occurs, and whether or not any catalysts are present in the reaction. Gorban and Yablonsky have suggested that the history of chemical dynamics can be divided into three eras. The first is the van 't Hoff wave searching for the general laws of chemical reactions and relating kinetics to thermodynamics. The second may be called the Semenov--Hinshelwood wave with emphasis on reaction mechanisms, especially for chain reactions. The third is associated with Aris and the detailed mathematical description of chemical reaction networks.
