Question

In the lower troposphere, ozone is one of the components ofphotochemical smog. It is generated in air when nitrogen dioxide,formed by the oxidation of nitrogen monoxide from car exhaust,reacts by the following mechanism.
(1) NO2(g) NO(g) + O(g)
(2) O(g) + O2(g) O3(g)
Assuming the rate of formation of atomic oxygen in step 1 equalsthe rate of its consumption in step 2, use the data below tocalculate the following quantities.
k1 = 8.0 10-3 s-1; [NO2] = 4.0 10-9 M
k2 = 1.0 106 L/mol
