The overall reaction NO2+COCO2+NO has a rate iw of rate =k[NO2][CO] at high temperature. Which of the following is consistent with this information? Aplausible mechanism is 1. NO2+NO2NO3+NO (slow) 2. NO3+CONO2+CO2 (fast) The rate limiting step must be bimolecular. CO2 is a reagent in the rate limiting step. A plausible mechanism is 1. NO2+NO2NO3+NO (fast equilibrium) 2. NO3+CONO2+CO2 (slow) The overall reaction could be the mechanism. That is, NO2+COCO2+NO is an elementary step
