The activation energy for a simple chemical reaction `A rarr B` is `E_(a)` in the forward reaction: The activation of the reverse reaction

Options

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

d

Explanation

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