NO2 absorbs energy from sunlight and breaks up into nitric oxide and free oxygen atom and this can be shown as-
NO2 (g) NO (g)+O (g)
Here the oxygen atom produced is very reactive and combines with oxygen molecule in the air to give rise to ozone.
O (g) +O2 (g) + M → O3 (g) + M
Here ‘M’ is an inert gas like Nitrogen gas and ozone gets produced during the formation of smog.
