The reaction between NO2 and co to produce no and CO2 is thought to occur in two steps:

Step 1: NO2 + NO2 → + NO + NO3
Step 2: NO3 + CO → NO2 + CO2

The experimental rate law is rate = k[NO2]2.

Required:
a. Write the equation for the overall reaction. do not include phase abbreviations.
b. Identify the intermediate(s).
