Writing Rate Laws For Reaction Mechanisms Using Rate Determining Step - Chemical Kinetics
 
12:18
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.

Short lecture on the rate-determining step of a sequence of chemical reactions. The rate determining step of a reaction is the elementary step which proceeds at the slowest rate. When sufficiently slow compared to the other steps, the rate law of the reaction is entirely determined by and equal to the rate law for the rate determining step.

The order of a reaction can describe, with respect to a reactant, the number of particles taking part in the rate-determining step. • Rate equations can only be determined experimentally. • The value of the rate constant (k) is affected by temperature and its units are determined from the overall order of the reaction. • Catalysts alter a reaction mechanism, introducing a step with lower activation energy. • Deduction of the rate expression for an equation from experimental data and solving problems involving the rate expression. • Sketching, identifying, and analysing graphical representations for zero, first and second order reactions. • Evaluation of proposed reaction mechanisms to be consistent with kinetic and stoichiometric data.

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.

Determining the Rate Law for a Mechanism with a Fast Equilibrium Step- Example
 
10:13
Dr. Shields shows how to derive the rate law from a multi-step kinetic mechanism involving a fast equilibrium step. Intermediates are discussed, as well as how to substitute for them using the fast equilibrium step. General Chemistry

Rate Law For SN1 SN2 E1 and E2 Reaction - Potential Energy Diagram & Mechanism
 
13:42
This chemistry video tutorial provides the rate law equation for SN1, SN2, E1, and E2 reactions. It also provides the mechanism as well as the potential energy diagrams that go along with it. The SN1 reaction is a first order nucleophilic substitution reaction where the rate depends on the concentration of the substrate only. In this example, a solvolysis reaction was used which occurs in 3 steps. The SN2 reaction is a single step concerted reaction mechanism and it's a second order nucleophilic substitution reaction where the rate depends on the concentration of the substrate and nucleophile. The E1 reaction is a first order elimination reaction where the rate depends on the substrate only. The E2 reaction is a second order elimination reaction where the rate depends on the concentration of the base and the substrate.
Determining the Rate Law from a Kinetic Mechanism (Pt  7)
 
14:50
Dr. Shields discusses the major concepts involved in chemical reaction mechanisms, including analyzing mechanisms involving a slow first step and those with a fast equilibrium step. Examples for writing the rate law for each type of kinetic mechanism will be discussed. General Chemistry.

First Order Reaction Chemistry Problems - Half Life, Rate Constant K, Integrated Rate Law Derivation
 
14:31
This chemistry video tutorial provides a basic introduction into first order reactions. It explains how to solve first order reaction problems such as calculating the final concentration and determining how long it will take for the concentration of the reactant to reach a certain. This video also explains how to calculate the half life of a first order reaction given the rate constant K. It discusses the units of the rate constant k for a first order reaction and it explains how to derive the integrated rate law expression for a first order reaction using techniques in calculus such as integration by separation of variables. This chemical kinetics tutorial contains plenty of example problems.

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.
