In the sequence of reaction, A →         k 1         B →         k 2         C →         k 3         D ,   where   k 3 > k 2 > k 1 , then the rate-determining step of the reaction is

Options

  1. AA → B
  2. BB → C
  3. CC → D
  4. DA → D

Correct answer

A. A → B

Step-by-step solution

In a chemical reaction, slowest step will be the rate-determining step. A →       k 1       B →       k 2       C →       k 3       D ∵ k 3 > k 2 > k 1 k 1 is minimum out of the given rate constants. So the slowest step is A → B , which will be the rate determining step of the reaction.
