Nitrogen Dioxide, NO₂ Will React with Carbon Monoxide, CO, to Form

Short Answer

Nitrogen dioxide, NO₂ will react with carbon monoxide, CO, to form nitric oxide, NO, and carbon dioxide, CO₂. A proposed mechanism is:
2NO₂ $\rarr$ NO₃ + NO
NO₃ + CO $\rarr$ NO₂ + CO₂
Experiments indicate that the rate of the reaction is independent of the CO concentration. Identify the rate determining step and derive the rate law consistent with the mechanism and experimental observation.
