Vedclass · Answer

(B) Catalytic converters are used in motor vehicles to reduce the emission of poisonous gases like carbon monoxide $(CO)$ and nitrogen oxides $(NO_x)$.These converters contain expensive metals like platinum,palladium,and rhodium as catalysts.Lead present in petrol acts as a poison to these catalysts,which inactivates or damages them,thereby preventing them from converting toxic gases into less harmful substances.Therefore,it is essential to use unleaded petrol in vehicles equipped with catalytic converters to ensure the catalyst remains active and functional.
