Question

The activation energy for a simple chemical reaction ` A to B ` is `E_(a)` in forward direction . The activation energy for reverse reaction
A. Is always double of `E_(a)`
B. Is negative of `E_(a)`
C. Is always less than `E_(a)`
D. Can be less than or more than `E_(a)`

Answer 1

Correct Answer - d
In exothermic and endothermic reactions will be more and less than `E_(a)` respectively .
