Identify the incorrect statement from the following:
1 Ozone absorbs the intense ultraviolet radiation of the sun
2 Depletion of ozone layer is because of its chemical reactions with chlorofluoro alkanes
3 Ozone absorbs infrared radiation
4 Oxides of nitrogen in the atmosphere can cause the depletion of ozone layer
Explanation:
The ozone layer, existing between 20 to \(35 \mathrm{~km}\) above the earth's surface, shield the earth from the harmful U.V. radiations from the sun. Depletion of ozone is caused by oxides of nitrogen \({{\rm{N}}_{\rm{2}}}{\rm{O + h}}\upsilon \to {\rm{NO + N}}\) reactive nitric oxide \(\mathrm{NO}+\mathrm{O}_{3} \longrightarrow \mathrm{NO}_{2}+\mathrm{O}_{2}\) \(\mathrm{O}_{3}+h v \longrightarrow \mathrm{O}_{2}+\mathrm{O}\) \(\mathrm{NO}_{2}+\mathrm{O} \longrightarrow \mathrm{NO}+\mathrm{O}_{2}\) \(2 \mathrm{O}_{3}+h v \longrightarrow 3 \mathrm{O}_{2}\) (Net reaction) The presence of oxides of nitrogen increase the decomposition of \(\mathrm{O}_{3}\).
