A reaction is exothermic, with E rxn = 40 kJ, and the transition state is 20 kJ

Question:

A reaction is exothermic, with ΔE_rxn = –40 kJ, and the transition state is 20 kJ higher in energy than the reactants. Sketch a reaction-energy profile consistent with this information, complete with labels for the distances representing ΔE_rxn and E_a.
