21. Shown to the right is the reaction coordinate diagram for the reaction: A + 2B → 2C. Which of the following statements are correct?
(A) Based on the reaction coordinate diagram, the rate law can be determined to be: rate = kA².
(B) The reaction mechanism consists of only one elementary step.
(C) Compound C is generated twice as fast as compound A is consumed.
(D) The overall reaction is endothermic.
(E) Increasing the temperature would result in the formation of fewer compound C.
