In today’s video we’ll look at the rate determining step, namely the slowest step in a reaction. We’ll begin with the factors that affect it and how we can predict the reaction mechanism with its help. Then we’ll proceed to the orders and learn how we can determine how many molecules of each species are involved in the rate determining step. Lastly, we’ll investigate orders and mechanism by looking at the reaction equation and conclude with an exam style question.

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.

Rate = k [product of the reactants in the rate determining step] but it could be more complex - see the vid. Make sure that when you "add up" the mechanism it equals your initial given equation. Was the stair that Dr Atkinson demised on his personal "rate determining step"?

This video lecture from Reaction Kinetics (F.Sc. first year Chemistry) covers the rate determining step. It is the slowest step of reaction mechanism which determines the rate law and overall rate of reaction. The concept has been demonstrated using an appropriate example.

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.

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.
