25PRACTICE PROBLEM
The gas-phase reaction between NO2 and CO was studied:
NO2(g) + CO(g) → CO2(g) + NO(g)
It was observed that the reaction takes place in two steps and it is second order in terms of NO2 and zero order in terms of CO. The mechanism for the reaction is:
Step 1: NO2(g) + NO2(g) → NO3(g) + NO(g) (slow)
Step 2: NO3(g) + CO(g) → NO2(g) + CO2(g) (fast)
Do these two reactions add to give the overall reaction?
