A) Ozone
B) \[C{{O}_{2}}\] and \[CO\]
C) \[C{{O}_{2}}\]and\[CO\]
D) \[S{{O}_{2}}\]and nitrogen oxide
Correct Answer: D
Solution :
Acid rain is caused by large scale emission of nitrogen oxides (NOx), sulphur oxides (SOx), volatile organic carbons and HCl from thermal power plants, industries and automobiles. Oxides of nitrogen and sulphur combine with water and oxygen and form nitric acid and sulphuric acid, respectively. \[2NO+\frac{3}{2}{{O}_{2}}\xrightarrow[{}]{{}}{{N}_{2}}{{O}_{2}}\] \[\begin{align} & {{N}_{2}}{{O}_{2}}+{{H}_{2}}O\xrightarrow[{}]{{}}2HN{{O}_{3}} \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Nitric\,acid) \\ \end{align}\] \[2S{{O}_{2}}+{{O}_{2}}\xrightarrow[{}]{{}}2S{{O}_{3}}\] \[\begin{align} & 2S{{O}_{3}}+2{{H}_{2}}O\xrightarrow[{}]{{}}2{{H}_{2}}S{{O}_{4}} \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Sulphuric\,acid) \\ \end{align}\]
