Ozone Decomposition: Ozone formation is faster during the day due to the action of sunlight on NO, molecules. Thus, 0,() accumulates in the troposphere and its concentration peaks sometime in the afternoon. During the night, orone reacts with NO(g) according to the following reaction: NO(g) + O2(g) - NO(g) + O2(b). This is a single step process with an activation energy - 12.5 kJ/mol and a AH--199.5 kJ/mol. PPS 5. Build potential energy diagram that represents the transformation of reactants...
