For the formation of B from A , heat liberated is $20 \mathrm{kJ} \mathrm{mol}^{-1}$. If the activation energy for the reaction $\mathrm{B} \rightarrow \mathrm{A}$ is 100 $\mathrm{kJ} \mathrm{mol}^{-1}$, then the activation energy (in $\mathrm{kJ} \mathrm{mol}^{-1}$ ) for the reaction $\mathrm{A} \rightarrow \mathrm{B}$ is
