37. Photo chemical smog is a resultant of the reaction among A.High concentration of NO2, O3, and CO in the evening B.CO, CO2 and NO2 at low temperature C.CO, O2 and peroxy acetyl nitrate in the presence of Sunlight D.NO2, O3 and peroxy acetyl nitrate in the presence of Sunlight
Answer: Option D Solution: Photochemical smog is a unique type of air pollution which is caused by reactions between sunlight and pollutants like hydrocarbons and nitrogen dioxide (NO and NO2). Other components of the photochemical smog include Ozone (O3) formaldehyde, peroxy benzoyl nitrate (PBzN), peroxy acetyl nitrate (PAN) and acrolein.
