The experimental rate law for the decomposition of nitrous oxide (N2O) to N2
and O2 is rate = k[N2O]^2. Two mechanisms are proposed:
I.N2O→N2+O
N2O+O→N2+O2
II.2N2O<=>N4O2
N4O2→2N2+O2
Which of the following could be a correct mechanism?
(A)Two of the above could be correct.
(B)Mechanism I with the first step as the rate-determining step.
(C)Mechanism II with the second step as the rate-determining step.
(D)Mechanism I with the second step as the rate-determining step.
參考答案:
(A)
請問有版友知道為什麼嗎？
謝謝

1F：推 sean30057:把題目給的兩個機構 推導出速率式 看有沒有和題目相符 11/23 22:20
2F：→ sean30057:有的話就可以選 11/23 22:21
