NEET Medical Online Video on Chemical Kinetics - Rate Law: Class 12th Chemistry
 
05:34
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.

Elementary Reactions
 
06:13
In this video Paul Andersen explains that elementary reactions are steps within a larger reaction mechanism. Colliding molecules require sufficient energy and proper orientation to break bonds and form new bonds. A unimolecular reaction mechanism requires one type of reactant and is a first-order reaction. A bimolecular reactions requires two molecules colliding and is a second-order reaction. Termolecular reactions are rare but are the colliding of three molecules. Do you speak another language?

The steady-state approximation says that the change in the concentration of a reaction intermediate over time is zero. This allows us to solve for the time-dependent concentration of the intermediate, and thus determine the overall reaction rate.

Chemical Kinetics Made Easy: Reaction Mechanisms Episode #09
 
08:31
Chemical Kinetics Made Easy: Reaction Mechanisms Episode #09 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.

16.1 Rate expressions and orders of reaction (HL)
 
07:07
16.1 Deduce the rate expression for a reaction from experimental data. Understandings: The order of a reaction can be either integer or fractional in nature. The order of a reaction can describe, with respect to a reactant, the number of particles taking part in the rate-determining step. Applications and skills: Deduction of the rate expression for an equation from experimental data and solving problems involving the rate expression.
