A) more relase of \[\text{N}{{\text{O}}_{\text{2}}}\] and \[\text{S}{{\text{O}}_{\text{2}}}\]by burning of fossil fuels
B) more relase of \[\text{C}{{\text{O}}_{2}}\]by burning of coal/wood cutting of forests and increasing popultions
C) excessive release of \[\text{N}{{\text{H}}_{\text{3}}}\]by coal gas/industries
D) excessive release of CO by incomplete combustion of carbonaceous fuels
Correct Answer: A
Solution :
The acid rain is intact the cocktail of \[{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\]and \[\text{HN}{{\text{O}}_{\text{3}}}\text{.}\]The \[\text{S}{{\text{O}}_{\text{2}}}\]and \[\text{N}{{\text{O}}_{\text{2}}}\]produced during the combustion of coal and petroleum reacts with water vapour and formed \[{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\]and \[\text{HN}{{\text{O}}_{\text{3}}}\]respectively. \[2S{{O}_{2}}+{{O}_{2}}\xrightarrow{{}}2S{{O}_{3}}\] \[S{{O}_{3}}+{{H}_{2}}O\xrightarrow{{}}{{H}_{2}}S{{O}_{4}}\] \[2NO+[O]\xrightarrow{{}}{{N}_{2}}{{O}_{5}}\] \[{{N}_{2}}{{O}_{5}}+{{H}_{2}}O\xrightarrow{{}}2HN{{O}_{3}}\] So, \[(N{{O}_{x}}),S{{O}_{2}}\]and volatile organic compounds are considered as acidic gases. \[\text{C}{{\text{O}}_{\text{2}}}\]released by fossil fuels, burning of coal/wood etc., is a green house gas. \[\text{CO}\] (released by automobiles, fossil fuels) and \[\text{N}{{\text{H}}_{3}}\] (from fertilizer, dye and lacquer industries) are found to be primary pollutant gas but have no role in acid rains.
