Chapter 14.5, Problem 3CP

Use the following information to answer questions 14.5.1 to 14.5.3: For the reaction:

$\text{A + B }\underset{}{\to }\text{C+ D}$

the experimental rate law is rate = $k{\left[\text{B}\right]}^{\text{2}}$.

Which of the following is a plausible mechanism for the reaction?

$\begin{array}{l}\text{a)}\hfill \\ \text{Step 1:A +B}\underset{}{\to }\text{ C + E }\left(\text{slow}\right)\hfill \\ \text{Step 2: E + A }\underset{}{\to }\text{D }\left(\text{fast}\right)\hfill \\ \text{b)}\hfill \\ \text{Step 1: B + B }\underset{}{\to }\text{ C +E}\left(\text{slow}\right)\hfill \\ \text{Step2: E + A }\underset{}{\to }\text{D + B }\left(\text{fast}\right)\hfill \\ \text{c)}\hfill \\ \text{Step 1: A + A }\underset{}{\to }\text{B +D }\left(\text{slow}\right)\hfill \\ \text{Step2: B +B }\underset{}{\to }\text{A+ C (fast)}\hfill \\ \text{d)}\hfill \\ \text{Step 1:B +B}\underset{}{\to }\text{C + E }\left(\text{slow}\right)\hfill \\ \text{Step 2: C + A}\underset{}{\to }\text{ D + B }\left(\text{fast}\right)\hfill \\ \text{e)}\hfill \\ \text{Step 1: A + B }\underset{}{\to }\text{D + E }\left(\text{slow}\right)\hfill \\ \text{Step 2: E + A }\underset{}{\to }\text{C }\left(\text{fast}\right)\hfill \end{array}$
