Which of the following srtatement above the advantage of masting of sulphide are before reduction is not true?

Options

A. Carbon and hydrongen are suitable reducing agents for metal sulphides
B. The `Delta""_(r)G^(0)` of the sulphide is greater than those for `CS_(2) and H_(2)S`
C. The `Delta""_(r)G^(0)` is negative for roasting for sulphide ore to oxide
D. Reasting of the sulphide to the oxide is thermodynamially feasible

Answer

A

Explanation

Carbon nd hydrogen are not suitable reducing agent of metla sulphides. They are suitable reducing ageng for metal oxide.
