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.
Assuming that the rate of formation of atomic oxygen in step 1 equals the rate of its consumption in step 2, calculate the concentration of atomic oxygen, (O).

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. Ozone Formation: NO:(), is formed by chemical reactions involving N2(g) and O-() at the high temperatures inside internal combustion engines in...

One of the components of smog is ozone,O3, a colorless, toxic gas. It is a very strong oxidizing agent and causes respiratory illnesses. Ozone is produced in the lower atmosphere due to the catalytic effect of nitric oxide, NO, a byproduct of the combustion process in car engines. However, in the upper atmosphere ozone is a very useful gas, because it absorbs ultraviolet radiation and protects the earth from this high energy, damaging radiation. It is referred to as the...
