Question

In an elementary exothermic reaction, how do the activation energy of the forward reaction ($E_f$) and the backward reaction ($E_b$) relate?

Answer: B

💡 Solution & Explanation

For an exothermic reaction, the overall enthalpy change ($\Delta H$) is negative. Since $\Delta H = E_f - E_b$, a negative value indicates that $E_f$ must be less than $E_b$.
