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) 50kJ
(b) 80kJ
(c) 60kJ
(d) 30kJ
