For an exothermic chemical process occurring in two as
(i) `A + B rarr X` (slow)
(ii) `X rarr AB` (fast)
The process of the reaction can be best described by

A

B

C

D

All are correct

Text Solution

Verified by Experts

The correct Answer is:
C
The reaction occuring in two steps has two activation energy peaks. The first step , being fast needs less activation eneergy . The second step being slow, needs more activation energy . Therefore, second peak will be higher than the first peak.
