The formation of dinitrogen pentoxide is described by the following chemical equation: \[ 2 \mathrm{NO}_{2}(g)+\mathrm{O}_{3}(\mathrm{~g}) \rightarrow \mathrm{O}_{2}(\mathrm{~g})+\mathrm{N}_{2} \mathrm{O}_{5}(\mathrm{~g}) \] Suppose a two-step mechanism is proposed for this reaction, beginning with this elementary reaction: \[ \mathrm{NO}_{2}(\mathrm{~g})+\mathrm{O}_{3}(\mathrm{~g}) \rightarrow \mathrm{NO}_{3}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~s}) \] Suppose also that the second step of the mechanism should be bimolecular. Suggest a reasonable second step. That is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the prop mechanism.
