Which of the following srtatement above the advantage of masting of sulphide are before reduction is not true?A. `Delta_(f) G^(Ө)` of the sulphide is greater than `CS_(2)` and `H_(2)S`.B. `Delta_(f) G^(Ө)` is negative for roasting of sulphide ore to oxideC. Roasting of the sulphide to oxide is thermodynamically feasibleD. Carbon and hydrogen are suitable reducing agents for metal sulphides.

Answer» Correct Answer - D
`Delta_(f) G^(Ө)` for sulphides `gt Delta_(f)G^(Ө)` for `CS_(2)` and `H_(2)S` and thus `C` and `H_(2)` cannot reduce metal sulphide.
