Question

Compare the following two potential energy diagrams for general reactions I andII. Which statement below is correct with respect to their corresponding enthalpy of reaction and their relative rates?
I. 
II.

Quizplus · Accepted Answer

Reaction I has a lower initial potential energy and a higher final potential energy than reaction II, indicating that it is exothermic. Reaction II has a higher initial potential energy and a lower final potential energy, indicating that it is endothermic. The activation energy for reaction II is lower than that of reaction I, indicating that reaction II proceeds at a faster rate.
