The experimental rate law for the decomposition of nitrous oxide (N2O) to N2 and O2 is Rate = k[N2O]2 . Two mechanisms are proposed: I. N2O  N2 + O N2O + O  N2 + O2 II. 2N2O N4O2 N4O2  2N2 + O2 Which of the following could be a correct mechanism? A) Mechanism I, with the first step as the rate-determining step. B) Mechanism I, with the second step as the rate-determining step as long as the first step is a fast equilibrium step. C) Mechanism II, with the second step as the ra...
