Chapter 13, Problem 13.23QP

You are running the reaction $2\text{A}+\text{B}\stackrel{}{\to }\text{C}+3\text{D}$. Your lab partner has conducted the first two experiments to determine the rate law for the reaction by the method of initial rates.

Experiment Number	Concentration of A (M)	Concentration of B(M)
1	0.0250	0.0330
2	0.0500	0.0330
3

Presuming that you can measure the initial rate of each experiment, which of the following concentrations for Experiment 3 would help you determine the rate law easily?

1. a [A] = 0.0330 M, [B] = 0.0330 M
2. b [A] = 0.0125 M, [B] = 0.0500 M
3. c [A] = 0.0250 M, [B] = 0.0400 M
4. d [A] = 0.0250 M, [B] = 0.0330 M
5. e [A] = 0.0500 M, [B] = 0.0330 M
