Question

Identify the incorrect statement from the following:

• A. Ozone absorbs the intense ultraviolet radiation of the sun
• B. Depletion of ozone layer is because of its chemical reactions with chlorofluoro alkanes
• C. Ozone absorbs infrared radiation
• D. Oxides of nitrogen in the atmosphere can cause the depletion of ozone layer

Answer 1

Answer: (C)

Ozone absorbs infrared radiation

Answer 2

Layer of $O_3$ in upper atmosphere absorbs UV radiations from sun, thus protects the human being living on the earth. Nitrogen oxides (particularly nitric oxide) combine very rapidly with ozone and there is, thus, the possibility that nitrogen oxides emitted from the exhaust systems of supersonic jet aeroplanes might be slowly depleting the concentration of the ozone layer in the upper atmosphere. The use of chlorofluoro carbon in aerosol and refrigerator and there, subsequent escape into the atmosphere is responsible for making holes in the ozone layer. Ozone at all does not absorb infrared radiation.
