The rate of the reaction O(g) + NO2(g) → NO(g) + O2(g) was studied at a certain temperature. This reaction is one step of the nitric oxide– catalyzed destruction of ozone in the upper atmosphere.
a. In one experiment, NO2 was in large excess at a concentration of 1.0 × 1013 molecules/cm3 with the following data collected:
What is the order of the reaction with respect to oxygen atoms?
b. The reaction is known to be first order with respect to NO2.
Determine the overall rate law and the value of the rate constant.
