Current Question (ID: 17844)

Question:

$\text{Pollution that occurs in the lowest layer of the atmosphere is:}$

Options:

1. $\text{Stratosphere pollution.}$
2. $\text{Ozone layer pollution.}$
3. $\text{Air pollution.}$
4. $\text{Troposphere pollution.}$

Solution:

$\text{Tropospheric pollution arises due to the presence of undesirable substances in the lowest layer of the atmosphere.}$ $\text{STEP 1- Oxides of sulphur, nitrogen, carbon, and hydrocarbons are the major gaseous pollutants.}$ $\text{Oxides of sulphur (SO}_2 \text{ and SO}_3\text{) and nitrogen (NO}_2, \text{ NO) are produced as a result of burning of fossil fuels (coal, automobile fuel).}$ $\text{These oxides react with water in the presence of atmospheric oxygen to form nitric acid (HNO}_3\text{) and sulphuric acid (H}_2\text{SO}_4\text{), which leads to the formation of ‘Acid rain’.}$ $\text{STEP 2-}$ $2\text{SO}_2{(s)} + \text{O}_2{(s)} + 2\text{H}_2\text{O}{(l)} \rightarrow 2\text{H}_2\text{SO}_4{(aq)}$ $4\text{NO}_2{(g)} + \text{O}_2{(g)} + 2\text{H}_2\text{O}{(l)} \rightarrow 4\text{HNO}_3{(aq)}$
