Question:

How can you determine the rate law of the following reaction?

2NO (g) + O2 (g) → 2NO2 (g)

Solution:

The rate of the reaction can be determined by

Rate = k[NO]2[O2]1

It can be measured by the rate of the reaction as a function of initial concentration by keeping the concentration of one of the reactants constant and changing the other reactant.
