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? (show all works) A) Mechanism I with the first step as the rate-determining step. B) Mechanism II with the second step as the rate-determining step if the first step is a fast equilibrium step. C) Mechanism I with the second step as the rate-determining step as long as the first step is a fast equilibrium step. D) At least two of the above choices (a-c) could be correct. E) None of the choices (a-c) could be correct.
