An exothermic reaction `ArarrB` has an activation energy of `17 kJ` per mole of `A`. The heat of the reaction is `40 kJ`. Calculate the activation energy for the reverse reaction `B rarr A`.

A

`60 kJ`

B

`57 kJ`

C

`75 kJ`

D

`90 kJ`

Text Solution

Verified by Experts

The correct Answer is:
B
Exothermic reaction

According to graph,
`E_(a(b))= E_(a(f)) + Delta H`
`= 17 + 40 = 57 kJ mol^(-1)`
