Vedclass · Answer

(A) The activation energy of the forward reaction is denoted as $E_{af}$ and the activation energy of the reverse reaction is denoted as $E_{ar}$.According to the relationship between enthalpy change and activation energy: $\Delta H = E_{af} - E_{ar}$.If $E_{af} = E_{ar}$,then $\Delta H = E_{af} - E_{af} = 0$.Therefore,for a reaction where the activation energies for the forward and reverse reactions are equal,the enthalpy change of the reaction is zero.
