Chapter 13, Problem 13.26QP

The hypothetical reaction

$\text{A}+\text{B}+\text{C}\stackrel{}{\to }\text{D}+\text{E}$

has the rate law Rate = k[A]²[B]. Which of the following changes would have the least effect on increasing the rate of this reaction?

1. a Doubling [A]₀ while keeping [B]₀, and [C]₀ constant.
2. b Doubling [B]₀ while keeping [A]_0, and [C]₀ constant.
3. c Doubling [C]₀ while keeping [A]₀ and [B]₀ constant.
4. d Increasing the rate constant by running the reaction at a higher temperature.
5. e Adding a catalyst to the reaction mixture.
