Problem

The oxidation of NONO to NO2NO_2 follows the rate law rate=k [NO]2 [O2]rate = k\,[NO]^2\,[O_2]. Two mechanisms are suggested. Mechanism I Step 1 (slow): NONO + O2O_2 → NO3NO_3 Step 2 (fast): NONO + NO3NO_3 → 2 NO22\,NO_2 Mechanism II Step 1 (slow): 2 NO2\,NO → N2O2N_2O_2 Step 2 (fast): N2O2N_2O_2 + O2O_2 → 2 NO22\,NO_2 Identify which mechanism (I or II) is compatible with the rate law and state one brief reason for your choice.
