Question
Relates to the Reaction Profile Diagram Shown Below: Which of the following statements are TRUE: a) There are two transition states (activated complexes) in this reaction. b) The energy of the second transition state is lower than the first transition state. c) The second activation energy is smaller than the first activation energy. d) Increasing the temperature will increase the activation energy of only the first step. e) The reaction is exothermic A. a and b only B. a and d only C. a, b and c only D. a, b, c, and d E. a, b, c, and eExplanation / Answer
(a) There are two transition state in this reaction. Representing with 'C'.
(b) The energy of second transition state is lower than the energy og first transition state.
(c) The second activation energy is smaller than the first activation energy.
(e) The reaction exothermic.
So, the answer is (E) a, b, c and e
SInce on increasing temperature, the initial energy of moleucles will be raised, so they require less amount of energy than that of at lower temperature. Becuase of this (d) is wrong.
