Chapter 12, Problem 15E

How much and in what direction will each of the following affect the rate of the reaction:

$\text{CO}\left(g\right)+{\text{NO}}_2\to {\text{CO}}_2\left(g\right)+\text{NO}\left(g\right)$ if the rate law for the reaction is rate $=k{\left[N{O}_2\right]}^2$?

(a) Decreasing the pressure of NO₂ from 0.50 atm to 0.250 atm.

(b) Increasing the concentration of CO from 0.01 M to 0.03 M.
