71. The reaction “A + 2B → 2 C” exhibits the rate law as following: Rate = k [A][B] 2
Which 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)
