Question
From where does ozone come in the photochemical smog?
Advertisements
Solution
NO2 absorbs energy from sunlight and breaks up into nitric oxide and free oxygen atom and this can be shown as-
\[\ce{NO2 (g) ->[hv] NO (g) + O (g)}\]
Here the oxygen atom produced is very reactive and combines with oxygen molecule in the air to give rise to ozone.
\[\ce{O (g) + O2 (g) + M -> O3 (g) + M}\]
Here ‘M’ is an inert gas like Nitrogen gas and ozone gets produced during the formation of smog.
