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

60kJ

B

57 kJ

C

75kJ

D

90kJ

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)`
