問題詳情
71. The reaction “A + 2B → 2 C” exhibits the rate law as following: Rate = k [A][B] 2Which of the following mechanisms could be consistent with this rate law?
(A) A + 2B → D (fast), D → 2 C (slow)
(B) 2B → D (fast), D + A → 2 C (slow)
(C) 2B → D (slow), A + D → E (fast), E → 2 C (fast)
(D) A + B ⇌ D (fast equilibrium), B + D → 2 C (slow)
(E) B ⇌ 2 D (fast equilibrium), D + A → C (slow)

釋疑說(A) D → 2C 為速率決定步驟,並無法獲得 Rate=k[A][B]2(B) D+A → 2C為速率決定步驟,也無法獲得 Rate=k[A][B]2因此僅有(D)選項為正確答案？
