Releted Question 4
Which of the following statements about the depletion of ozone layer is correct ?
A.
The problem of ozone depletion is less serious at poles because $$N{O_2}$$ solidifies and is not available for consuming $$CI{O^ \bullet }$$ radicals.
B.
The problem of ozone depletion is more
serious at poles because ice crystals in the clouds over poles act as catalyst for photochemical reactions involving the decomposition of ozone of $$C{l^ \bullet }$$ and $$CI{O^ \bullet }$$ radicals.

stratosphere.
D.
Oxides of nitrogen also do not react with ozone in stratosphere.
