Chapter 13, Problem 67RQ

The following data were collected for the reaction $M+N\to P+Q:$:

Initial Concentrations $\left({\text{mol L}}^{\text{-1}}\right)\left[\text{M}\right]\text{ [N]}$		Initial Rate of Reaction ${\text{(mol L}}^{\text{-1}}{\text{s}}^{\text{-1}}\text{)}$
0.010	0.010	$\text{2}\text{.5 }\times {\text{10}}^{\text{-3}}$
0.020	0.010	$\text{5}\text{.0 }\times {\text{ 10}}^{\text{-3}}$
0.020	0.030	$\text{4}\text{.5 }\times {\text{ 10}}^{\text{-2}}$

What is the rate law for the reaction? What is the value of the rate constant (with correct units)?
