Question

1 Activation energy of the exothermic reaction A B
is 40 kJ mol-1. The heat of reaction is 15 kJ mol-1. What
is the activation energy for the backward reaction ?​

Answer 1

Answer:

Activation energy for the backward reaction=Activation energy of the forward reaction+enthalpy

                          =40+15

                          =55kJmol⁻¹

Activation energy for the backward reaction is 55kJmol⁻¹
