The reaction $\displaystyle \mathrm{X} \rightarrow \mathrm{Y}$ is an exothermic reaction. Activation energy of the reaction for X into Y is $\displaystyle 150 \mathrm{~kJ} \mathrm{~mol}^{-1}$. Enthalpy of reaction is $\displaystyle 135 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The activation energy for the reverse reaction, Y→X will be :
Official answer
(2)
$\displaystyle 285 \mathrm{~kJ} \mathrm{~mol}^{-1}$
