Vedclass · Answer

(C) The reduction of metal sulphides to metals is thermodynamically unfavorable compared to the reduction of metal oxides. Metal oxides are generally easier to reduce using common reducing agents like $C$ or $CO$ because the formation of $CO_2$ is highly exothermic. In contrast,the reduction of metal sulphides is difficult and often requires more energy. Therefore,sulphide ores are first converted into metal oxides through a process called roasting,which makes the subsequent reduction to metal much more efficient.

List-$I$	List-$II$
$(I)$ Calcination	$a. Fe_2O_3 \cdot nH_2O \rightarrow Fe_2O_3 + nH_2O$
$(II)$ Roasting	$b. 2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$
$(III)$ Flux	$c. SiO_2 + FeO \rightarrow FeSiO_3$
$(IV)$ Thermite	$d. Cr_2O_3 + 2Al \rightarrow Al_2O_3 + 2Cr$
