Chapter 11, Problem 93QAP

Consider the following activation energy diagram.

Which of the following statements about the diagram are true?

(a) $E_{\text{a}}\left(\text{forward}\right)<E_{\text{a}}\left(\text{reverse}\right)$(b) B represents the activation energy of the forward reaction.

(c) Energy $\left(\Delta H\right)$for the reaction is $\text{A}-\text{C}$.

(d) $E_{\text{a}}\left(\text{forward}\right)=\text{B}-\text{A}$(e) $E_{\text{a}}\left(\text{forward}\right)=E_{\text{a}}\left(\text{reverse}\right)-\text{C}$
