Consider the reaction E + F †’ G + H, which has the following reaction coordinate diagram.

Which one of the following statements is true?
a. The activation energy is greatest for the forward reaction.
b. The reactants are at a lower energy than the products.
c. The reaction is endothermic.
d. The rate of the forward reaction would be slowed by an increase in temperature.
e. If the rate law for the reaction is Rate = k[E]2[F], then doubling the concentration of E will cause the rate to increase by a factor of 4 (that is, the reaction will proceed four times faster).
