Chapter 14, Problem 93AP

The reaction of ${\text{G}}_{\text{2}}{\text{with E}}_{\text{2}}$ to form 2EG is exothermic, and the reaction of ${\text{G}}_{\text{2}}{\text{with X}}_{\text{2}}$ to form 2XG is endothermic. The activation energy of the exothermic reaction is greater than that of the endothermic reaction. Sketch the potential-energy profile diagrams for these two reactions on the same graph.
