Problem

Consider the reaction:

2 AB → C+ 2 BC

The following mechanism has been proposed.

2 AB → A2B2                       slow

second step                         fast

A student is testing this mechanism for plausibility, which of the following statements is/are true?

i. the experimental rate law should be Rate = k[AB] 2[C2]

ii. the experimental rate law should be Rate = k[AB] 2

iii. A2B2 + C2 → A2 + 2 BC could be fast step

a. i only

b. ii only

c. i and iii

d. i and ii

e. ii and iii
