3. Based on results from Question 2, what two collisions (called elementary steps) are required to convert reactants to products.
4. Based on results from Question 2, propose a step-by-step process (a mechanism) that converts reactants to products.
5. Describe the role of G2 in the overall mechanism of the reaction between G and B.
6. A possible mechanism for the reaction is the one step collision between three reacting particles:
G + G + B ---> G2B.
Is this a likely mechanism for this reaction? Why or why not.
7. Suggest a possible mechanism for the following reaction:
NO2 + CO ---> NO + CO2
