Chapter 11, Problem 15QRT

For the reaction

$2{\text{NO}}_2\left(\text{g}\right)\to 2\text{NO}\left(\text{g}\right)+{\text{O}}_2\left(\text{g}\right)$

make qualitatively correct plots of the concentrations of NO₂(g), NO(g), and O₂(g) versus time. Draw all three graphs on the same axes; assume that you start with NO₂(g) at a concentration of 1.0 mol/L. Explain how you would determine, from these plots,

1. (a) the initial rate of the reaction.
2. (b) the final rate (that is, the rate as time approaches infinity).
