Both Statement $I$ and Statement $II$ are correct.

Vedclass · Answer

(A) In metallurgy,sulphide ores are first converted into oxides by roasting because it is thermodynamically easier to reduce metal oxides than metal sulphides.$2 ZnS + 3 O_2 \rightarrow 2 ZnO + 2 SO_2$Metal oxides are easier to reduce using carbon because the formation of $CO_2$ is more favorable and $CO_2$ is a stable gas,whereas the reduction of sulphides with carbon is difficult and often leads to the formation of $CS_2$,which is less stable and harder to remove.Therefore,both Statement-$I$ and Statement-$II$ are correct.

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	$d. Cr_2O_3 + 2Al \rightarrow Al_2O_3 + 2Cr$

Given below are two statements:
Statement-$I$ : In the metallurgy process,sulphide ore is converted to oxide before reduction.
Statement-$II$ : Oxide ores in general are easier to reduce.
In the light of the above statements,choose the most appropriate answer from the options given below :
