Assertion (A): Different assumptions about the rate determining step give different rate expressions for the same mechanism.
Reason (R): Each assumption puts a different combination of adsorption terms into the denominator.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the origin: fitting data to several candidate expressions and choosing the best is how the controlling step is usually inferred. Each gives a distinct denominator. Discriminating between them takes real evidence.
