Please answer #7 and #8 only,
Thank you!
Ozone Decomposition: Ozone formation is faster during the day due to the action of sunlight on NO2 molecules. Thus, Os(g) accumulates in the troposphere and its concentration peaks sometime in the afternoon. During the night, ozone reacts with NO(g) according to the following reaction: NO(g) + Os(g) = NO2(g) + Ox(g). This is a single-step process with an activation energy E. = 12.5 kl/mol and a AH..=-199.5 kJ/mol. 5. Build potential energy...
