Vedclass · Answer

(A) The presence of particulate matter in polluted air catalyses the oxidation of sulphur dioxide to sulphur trioxide: $2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$.This reaction is also promoted by ozone $(O_3)$ and hydrogen peroxide $(H_2O_2)$:$SO_{2(g)} + O_{3(g)} \rightarrow SO_{3(g)} + O_{2(g)}$$SO_{2(g)} + H_2O_{2(l)} \rightarrow H_2SO_{4(aq)}$Thus,particulate matter,ozone,and hydrogen peroxide all enhance the pollution caused by oxides of sulphur.

List-$I$	List-$II$
$(A)$ Lead	$(I)$ $500 \text{ ppm}$
$(B)$ Sulphate	$(II)$ $50 \text{ ppm}$
$(C)$ Nitrate	$(III)$ $50 \text{ ppb}$

The pollution due to oxides of sulphur gets enhanced due to the presence of:
$(a)$ particulate matter
$(b)$ ozone
$(c)$ hydrocarbons
$(d)$ hydrogen peroxide
