Given reasons for the following: NO (g) released by jet aeroplanes is slowly depleting the ozone layer.

NO emitted from the exhausts of supersonic jet aeroplanes readily combine with ozone to form NO₂ and O₂. NO(g) + O₃(g) → NO₂(g) + O₂(g) Since supersonic jets fly in the stratosphere near the ozone layer, the NO gas released is responsible for the depletion of the ozone layer.
