Question

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

\[\ce{2NO(g) + O2(g) -> 2NO2(g)}\]

Answer 1

The rate of the reaction can be determined by

Rate = \[\ce{k{[NO]}^{2}{[O2]}^{1}}\]

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.
