11PRACTICE PROBLEM
Photochemical reactions are catalyzed by the absorption of light by one of the reactants. For example, the formation and decomposition of ozone shown below.
step 1: NO2 + hv → NO + O*
step 2: O* + O2 → O3
step 3: O3 + NO → NO2 + O2
The enthalpy changes and activation energies for these two reactions are tabulated as follows.
Draw the energy diagram showing the sequence for step 2 and step 3
