NEET levelSingle correct optionDifficulty 1 of 3ev065

Nitric oxide released by supersonic jet aircraft flying in the stratosphere can destroy ozone through the reaction

A $NO + N X_{2} N X_{2} O + N$
B $NO + O X_{3} NO X_{2} + O X_{2}$
C $NO + H X_{2} O HNO X_{2} + H$
D $NO + O X_{2} NO X_{3}$

Answer: B

Nitric oxide takes an oxygen atom from ozone to give

NO X_{2}

and

O X_{2}

. The

NO X_{2}

then reacts with atomic oxygen to regenerate NO, so NO acts as a catalyst.
