A reaction of importance in the formation of smog is that between ozone and nitrogen monoxide described by
O3(g)+NO(g)⟶O2(g)+NO2(g)O3(g)+NO(g)⟶O2(g)+NO2(g)
The rate law for this reaction is
rate of reaction=?[O3][NO]rate of reaction=k[O3][NO]

In the lower troposphere, ozone is one of the components of photochemical smog. It is generated in air when nitrogen dioxide, formed by the oxidation of nitrogen monoxide from car exhaust, reacts by the following mechanism: k1 1) NO2(g)........................................> NO(g) + O(g) k2 2) O(g) + O2(g)...........................> O3(g), where k1= 6.0 x 10^-3 s^-1 ; k2= 1.0 x 10^6 L/mol.s ; (NO2) = 1.0 x 10^ -9 M and (O2) = 1.0 x 10 ^-2 M.

Photochemical Smog Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases, such as nitrogen oxides (e.g., NO, NO:) to form harmful substances such as ozone (0). These substances participate in a reaction cycle that determines the concentration of pollutants at different times during the day.
