[References] This question has multiple parts. Work all the parts to get the most points. a The reaction of NO2 (g) and CO(g) is thought to occur in two steps: Step 1 Slow NO2 (g) + NO2 (9) → NO(g) + N03 (g) Step 2 Fast NO3 (9) + CO(g) → NO2(g) + CO2(g) Add the elementary steps to give the overall, stoichiometric reaction.
