Problem

In an uncatalyzed elementary reaction, the reactants are assigned an energy of 0 kJ mol−10\,\text{kJ mol}^{-1}. The uncatalyzed activation energy for the forward process is 95 kJ mol−195\,\text{kJ mol}^{-1}, and the products are at −40 kJ mol−1-40\,\text{kJ mol}^{-1}. A catalyst lowers the forward activation energy by 30 kJ mol−130\,\text{kJ mol}^{-1} without affecting ΔE\Delta E. Determine (i) the forward activation energy for the catalyzed pathway, (ii) the reverse activation energy for the uncatalyzed pathway, and (iii) the reverse activation energy for the catalyzed pathway. Report each value in kJ mol−1^{-1}.
