The elementary gas-phase reaction

\mathrm{NO}(g) + \mathrm{O_3}(g) \rightarrow \mathrm{NO_2}(g) + \mathrm{O_2}(g)

follows the stoichiometry shown. (1) Write the rate law for this elementary step. (2) State the units of the rate constant

k

when concentration is expressed in

\mathrm{mol\,L^{-1}}

and time in

\mathrm{s}
