Vedclass · Answer

(B) Catalytic converters are used in automobiles to reduce the emission of poisonous gases like carbon monoxide and nitrogen oxides. These converters contain expensive metals like platinum,palladium,and rhodium as catalysts. Lead $(Pb)$ present in petrol acts as a catalyst poison. When lead enters the catalytic converter,it binds to the active sites of the catalyst,thereby inactivating it and rendering the converter ineffective.
