A proposed mechanism for the reaction of NO2 and CO is
Step 1: Slow, endothermic:
2 NO2 (g) → NO (g) + NO3 (g)
Step 2: Fast, exothermic:
NO3 (g) + CO (g) → NO2 (g) + CO2 (g)
Overall reaction, exothermic:
NO2 (g) + CO (g) → NO (g) + CO2 (g)
a. Identify each of the following as a reactant, product, or intermediate:
1. NO2(g)
2. CO(g)
3. NO3(g)
4. CO2(g)
5. NO(g)
b. Draw a reaction coordinate diagram for this reaction. Indicate on this drawing the activation energy for each step and the overall enthalpy change.
