Vedclass · Answer

(B) Catalytic converters contain expensive metals such as platinum,palladium,and rhodium which act as catalysts to reduce the emission of poisonous gases like carbon monoxide and nitrogen oxides.Lead present in petrol acts as a catalyst poison.It binds to the active sites of these metals,thereby inactivating them and rendering the catalytic converter ineffective.Therefore,the use of unleaded petrol is recommended for vehicles equipped with catalytic converters.
