Photochemical smog / oxidising smog -

Occurs in warm, dry and Sunny climate

- wherein

Mixture of formaldehyde, acrolein, nitric oxide, ozone, and proxy-acyl nitrates (PAN)

 

 

Photochemical smog formation -

Emission of nitrogen oxides and hydrocarbons from automobiles exhausts and solar energy by chain of reactions. NO3 and O3 react with unburnt hydrocarbons to produce formaldehyde, aerolein and proxy-acyl nitrates (PAN)

- wherein

NO_{2}(g)\rightarrow NO\left ( g \right )+O\left ( g \right )

O\left ( g \right )+O_{2}\rightleftharpoons O_{3}(g)

NO(g)+O_{3}\left ( g \right )\rightarrow NO_{2}\left ( g \right )+O_{2}\left ( g \right )

3CH_{4}+2O_{3}\rightarrow 3CH_{2}= O\,(formaldehyde)+3H_{2}O

CH_{2}= CHCH= O\, (Acrolein)

CH_{3}COONO_{2}

            \parallel

            O  (PAN)

 

As we know Fxon's (CFC'S) are not common component of the photo chemical smog .


Option 1)

 

Option 2)

CH_{2}= CHCHO

Option 3)

CF_{2}Cl_{2}

Option 4)

O_{3}
