(a) Explain how the graphs indicate that the reaction is second order. (c) Consider two possibite mechanisms for the decomposition reaction. (i) Is the rate law described by mechanism I shown below consistent with the rate law you wrote in part (b) ? Justify your answer. Mechanism I Step 1: NO2(g)+NO2(g)NO(g)+NO3(g) slow Step 2: NO3(g)NO(g)+O2(g) fast (ii) Is the rate law deseribed by mechanism II shown below consistent with the rate law you wrote in part (b) ? Justify your answer. Mechanism II Step 1: NO2(g)+NO2(g)N2O4(g) fast equilibrium Step 2: N2O4(g)2NO(g)+O2(g) slow (a) Explain how the graphs indicate that the reaction is second order.
