Problem

Nitrogen dioxide can be produced by reacting oxygen and nitrogen monoxide:

\text{O}_2(\text{g}) + 2\text{NO}(\text{g}) \rightarrow 2\text{NO}_2(\text{g})

A student performed a series of experiments to determine the order of reaction with respect to

\text{O}_2

and

\text{NO}

. The results are given in the table.

Experiment	Initial $[\text{O}_2] / \text{mol dm}^{-3}$	Initial $[\text{NO}] / \text{mol dm}^{-3}$	Temperature / K	Initial rate / $\text{mol dm}^{-3} \text{s}^{-1}$
1	0.02	0.013	298	0.0033
2	0.02	0.013	318	0.0376
3	0.04	0.013	298	0.0066
4	0.08	0.026	298	0.0528

Determine the order of reaction with respect to each reactant and, hence, write the rate equation.
