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...
