Problem

Consider the two-step mechanism below, where all energy values are per mole: Step 1: A

\rightarrow

E_{a1,\text{fwd}} = 60\,\text{kJ}

\Delta H_1 = +15\,\text{kJ}

Step 2: B

\rightarrow

E_{a2,\text{fwd}} = 95\,\text{kJ}

\Delta H_2 = -40\,\text{kJ}

Provide the activation energies for the reverse directions of Step 1 and Step 2, respectively, in

\text{kJ}
