Ozone in the stratosphere can be depleted in catalyzed reactions. The overall reaction for this exothermic process is given by:

O3 +O→2O2, via the mechanism:

NO+O3 →NO2 +O2

NO2 +O→NO+O2

  1. Is this mechanism a chain reaction? Why or why not?

  2. Identify both the catalyst and the reactive intermediate in this mechanism.

  3. Draw to a relative scale the potential energy vs. reaction coordinate diagram for both the uncatalyzed reaction and the catalyzed reaction. Label transition states, activation energy, and reactive intermediates where appropriate.
