Please answer #3 and #4
only
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...
