Vedclass · Answer

(A) $Pb$ (lead) acts as a catalytic poison. In many industrial processes,such as the catalytic converters used in automobiles,the presence of lead $(Pb)$ binds to the active sites of the catalyst (like platinum or palladium). This prevents the reactants from binding to the catalyst,thereby deactivating it and rendering it ineffective. Therefore,$Pb$ deactivates catalysts.
