Vedclass · Answer

(C) Catalytic converters in automobiles use noble metals like $Pt$,$Pd$,and $Rh$ as catalysts to reduce the emission of harmful gases.These converters facilitate the conversion of toxic gases like carbon monoxide $(CO)$ and nitrogen oxides $(NO_x)$ into less harmful gases like carbon dioxide $(CO_2)$ and nitrogen gas $(N_2)$.Specifically,the catalyst helps in the reduction of $NO_2$ (a major component of $NO_x$) to $N_2$,preventing its release into the atmosphere.Therefore,$(X)$ is a metal like $Pt$ or $Pd$ and $(Y)$ is $NO_2$.

$A$ metal catalyst $(X)$ is used in the catalytic converter of automobiles. This prevents the release of gas $(Y)$ into the atmosphere. What are $(X)$ and $(Y)$ respectively?
