Vedclass · Answer

(D) The reduction of metal sulphides is thermodynamically difficult because the enthalpy of formation of metal sulphides is less negative than that of metal oxides. Conversely,the enthalpy of formation of $CO_2$ is more negative than that of $CS_2$,making carbon a suitable reducing agent for metal oxides but not for metal sulphides. Therefore,sulphide ores are first converted into metal oxides by roasting,which are then easily reduced to the metal.
