Detailed explanation-1: -Complete Answer:-Photochemical smog contains pollutants along with the presence of nitrogen dioxide which reacts with sunlight present to form a brown haze above cities. Carbon dioxide gas does not contribute to the formation of smog in cities.
Detailed explanation-2: -Photochemical smog is also called Los Angeles Smog. This kind of smog requires neither smoke nor fog.
Detailed explanation-3: -Carbon monoxide accelerates the reaction as measured by nitric oxide oxidation or ozone formation. This finding has relevance to photochemical smog formation.
Detailed explanation-4: -Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.
Detailed explanation-5: -The major undesirable components of photochemical smog are nitrogen dioxide (NO2), ozone (O3), PAN (peroxyacetylnitrate), and chemical compounds that contain the –CHO group (aldehydes).
