Vedclass · Answer

(A) Catalytic converters are used in motor vehicles 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 present in petrol acts as a poison for these catalysts and inactivates them,thereby reducing the efficiency of the catalytic converter.Therefore,vehicles equipped with catalytic converters must use unleaded petrol to ensure the catalyst remains active.Thus,both assertion $A$ and reason $R$ are correct,and $R$ is the correct explanation of $A$.

$A$ - Motor vehicles equipped with catalytic converters should use unleaded petrol.
$R$ - Lead in the petrol inactivates the catalyst.
