Task: Balance each equation in the mechanism below that shows the formation of ozone (O3) in the atmosphere.
Note: some of the equations below may already be balanced!
(i) In the first step, nitrogen and oxygen combine to form nitrogen monoxide
N2 + O2 ---> NO
(ii) In the next step, nitrogen monoxide reacts with more oxygen to produce nitrogen dioxide
NO + O2 ---> NO2
(iii) When nitrogen dioxide in the upper atmosphere absorbs UV radiation from the sun, it
decomposes to nitrogen monoxide and an oxygen atom
NO2 + UV light ---> NO + O
(iv) In the final step, the highly reactive oxygen atom combines with an oxygen molecule to
form ozone
O + O2 ---> O3
