Given reaction 2 NO2 + O2 --> N2O5 + O2. It is believed that a species with the formula NO3 is involved in the mechanism, and the observed rate law for the overall reaction is rate = k[NO2][O3]. Propose a mechanism for this reaction that includes the species NO3 and is N2O5 is consistent with the observed rate law.

Expert Answer
The rate equation shows us how many atoms or molecules of a certain chemical is present in the slow step. In the above rate equation, it shows that only 1 NO2 and 1 O3 is involved in the slow step. Therefore, when choosing the answer, you should look answer which have only 1 NO2 molecule and 1 O3 molecule in the slow step.
NO2 + O3 => NO3 + O2 (slow)
NO3 + NO2 => N2O5 (fast)
NO3 + NO2 => N2O5 (fast)
