The rate equation for a reaction mechanism is determined by the slowest step (the rate-determining step). The given mechanism is: 1. N_2O_5(g) N_2O_3(g) + O_2(g) (Slow step) 2. N_2O_3(g) NO(g) + NO_2(g) (Fast step) 3. NO(g) + N_2O_5(g) 3NO_2(g) (Fast step) The slow step is the first step: N_2O_5(g) N_2O_3(g) + O_2(g) For an elementary step, the rate law can be written directly from the stoichiometry of the reactants in that step. In this slow step, one molecule of N_2O_5 reacts. Therefore, the rate equation for the reaction is: Rate = k[N_2O_5] The rate equation for the reaction is Rate = k[N_2O_5].
