(D) The activation energy for the forward reaction $(E_f)$ and the activation energy for the backward reaction $(E_b)$ are related to the enthalpy of the reaction $(\Delta_r H)$ by the equation: $\Delta_r H = E_f - E_b$. For an exothermic reaction, the enthalpy change is negative, meaning $\Delta_r H Substituting this into the equation, we get $E_f - E_b < 0$, which implies $E_f < E_b$.
