5.20 In the troposphere NO reacts with O3 to produce NO2 and O2, Nitric oxide also reacts. with the hydroperoxyl (HO2) radical to produce NO2 and OH. In turn, NO2 is photolyzed rapidly to produce NO and atomic oxygen. The atomic oxygen quickly combines with O2 (when aided by an inert molecule M) to produce O3. (a) Write down balanced chemical equations to represent each of these four chemical reactions. (b) Write down differential equations to represent the time dependencies of the concentrations of NO, 03, NO2,HO2,0H, and O in terms of appropriate constituent concentrations and rate coefficients. (c) Neglecting hydroxyl-hydroperoxyl chemistry and assuming steady-state conditions, derive an expression for the concentration of 03 in terms of the concentrations of NO2 and NO and appropriate rate coefficients.
