Chapter 11, Problem 12QAP

A reaction has two reactants Q and P. What is the order with respect to each reactant and the overall order of the reaction described by the following rate expressions?

(a) $\text{rate}=k_1$(b) $\text{rate}=k_2{\left[\text{P}\right]}^2\left[\text{Q}\right]$

(c) $\text{rate}=k_3{\left[\text{Q}\right]}^2$

(d) $\text{rate}=k_4\left[\text{P}\right]\left[\text{Q}\right]$
