Solution: We can use a 2-D potential energy surface to depict the progress of a reaction. Given the following: a. The y-axis should be labeled as ___________ and the x-axis should be labeled as ____________ . b. From the labels A-G, _______ is/are the reactant(s), _______ is/are the product(s), _______ is/are the reaction intermediates, and _______ is/are the transition states (activated complexes). c. The reaction profile depicts _____ number of elementary steps. d. Step ____ is rate-limiting. e. The overall reaction is __________ (endothermic, exothermic). f. Write the equation for the overall reaction:  g. Explain how the addition of a catalyst will change the reaction depicted above.
