Problem

A reaction proceeds in two elementary steps with the following potential-energy data (all energies are relative to the reactants): • Transition state 1: 80 kJ • Intermediate: 30 kJ • Transition state 2: 60 kJ • Products: −5 kJ What is the activation energy for the rate-determining step of the forward reaction? a)

50\ \text{kJ}

80\ \text{kJ}

60\ \text{kJ}
