Which of the following statements about the reduction is not true ?A.

1.	Which of the following statements about the reduction is not true ?A. `Delta_(f)G^(@) "of the sulphide is greater than those of "CS_(2) ""and"""H_(2)S`B. `Delta_(f)G^(@)` is megative for roasting of sulphide ore to oxideC. Roasting of sulphide to oxide is thermodynamically feasibleD. Carbon and hydrogen are suitable reducing agents for metal sulphides
Answer» (d) both C and `H_(2)` are not suitable for reducing sulphide ore because `Delta_(f)G^(@)` of metal sulphide is more than that of `CS_(2)` and `H_(2)S` which will be formed as a result of reduction.
