Vedclass · Answer

(B) Catalytic converters,which contain expensive metals like platinum,palladium,and rhodium as catalysts,are fitted into automobiles to reduce the emission of poisonous gases.These converters convert unburnt hydrocarbons into $CO_{2}$ and $H_{2}O$.Motor vehicles equipped with catalytic converters must use unleaded petrol because lead in petrol inactivates the catalyst.Inactivation of the catalyst leads to an increase in hydrocarbon emissions,which severely impacts the environment.Furthermore,lead accumulates in bones,blood,and soft organs,adversely affecting the kidneys,liver,nervous system,and other vital organs.
