Question

Ozone reacts with nitrogen dioxide to porduce oxygen anddinitrogen pentoxide.                                       O3(g) + 2NO2(g) -----> O2(g) +N2O5(g) The proposed mechanism is                                         O3 + NO2 ------> NO3 +O2   (slow)                                                                                     NO3 + NO2 ----->N2O5 (fast) What is the rate lave predicted by this mechanism?

Explanation / Answer

The rate law is based off of the slowest step. Based on the "slow" equation: Rate = k[O3][NO2] Noticed that since both O3 and NO2 are in the equilibrium equation(the first equation), you are done. Final answer: Rate =k[O3][NO2]
