Vedclass · Answer

(B) The correct matches are as follows:$(1)$ Electrostatic precipitator: It is used to remove over $99\%$ of particulate matter present in the exhaust from a thermal power plant. Thus,$(1-c)$.$(2)$ Scrubber: It is used to remove harmful gases like sulfur dioxide $(SO_2)$ from industrial exhaust by passing it through a spray of water or lime. Thus,$(2-a)$.$(3)$ Catalytic converter: These are fitted into automobiles for reducing the emission of poisonous gases. They convert unburnt hydrocarbons into $CO_2$ and $H_2O$,and carbon monoxide and nitric oxide into $CO_2$ and $N_2$ gas. Thus,$(3-b)$.Therefore,the correct sequence is $(1-c, 2-a, 3-b)$.

Column-$I$	Column-$II$
$(1)$ Electrostatic precipitator	$(a)$ Removes gases like $SO_2$
