A catalyst decreases the activation energy of a particular exothermic reaction by 38 kJ/mol, to 56 kJ/mol. Assuming that the mechanism has only one step, and that the products are 47 kJ lower in energy than the reactants, sketch approximate energy-level diagrams for the catalyzed and uncatalyzed reactions.
What is the activation energy for the uncatalyzed reverse reaction?
