Problem

The following mechanism has been proposed for the reaction, A2 + 2 B → 2 P.  What is the order of the reaction in terms of A2?

1. A2 <=> 2 A     Fast

2. A + B → P       Slow


A. 3/2
B. 1
C. 2
D. 1/4
E. 1/2

Solution

We're being asked to determine the order of the reaction in terms of A2. The following mechanism has been proposed for the reaction, A2 + 2 B → 2 P:

1. A2 <=> 2 A     Fast
2. A + B → P       Slow


When a reaction mechanism is given, the rate law can be determined using the slow step in the reaction mechanism.
