Consider the following representation of a reaction mechanism.

Step 1: A+A → C+E (slow)
Step 2: E + B → A+D (fast)
Overall reaction: A + B → C + D

What should appear in the rate law for the reaction above?

A) only A and B because they are reactants in the overall reaction

B) only C and C because they are products in the overall reaction

C) only A because it is the reactant in the rate-determining step

D) only E and B because they are the reactants in the rate-determining step​

Answer:

The rate determining step is step 1

Explanation:

In the rate law for the given reaction,

  • only A appears because it is the reactant in the rate-determining step.

So, option C is correct one.

Which step is rate determining steps?

  • The slowest steps is rate determining step of the reaction.
  • It is because in rate determining step the intermediate is formed.

What is intermediate ?

  • The short lived species formed in the mechanism of reaction is called intermediate.
  • The intermediates is formed in slowest step because it is unstable species.

What is rate law for the reaction?

  • The rate law is also known as rate equation
  • It is the expression that provides relationship between rate and concentration of the reaction in a chemical reaction.
  • The rate law is determined by the experimentally.
  • If the reaction occurs in multi steps then the rate of the reaction is depends upon slowest step of the reaction.
