Question:

The reaction 2NO(g) + O2(g) → 2NO2(g) exhibits the rate law Rate = k[NO]2[O2] Which of the following mechanisms is consistent with this rate law?
a. NO + O2 → NO2 + O Slow
O + NO → NO2 Fast
b. NO + O2 ⇌ NO3 Fast equilibrium
NO3 + NO → 2NO2 Slow
c. 2NO → N2O2 Slow
N2O2 + O2 → N2O4 Fast
N2O4 → 2NO2 Fast
d. 2NO ⇌ N2O2 Fast equilibrium
N2O2 → NO2 + O Slow
O + NO → NO2 Fast
