Which of the following statements, about the advantage of roasting of – InterviewSolution

1.	Which of the following statements, about the advantage of roasting of sulphide ore before reduction is not true ?
Answer» `DeltaG_(F)^(@)` of sulphide is greater than those for `CS_(2)` and `H_(2)S`. `DeltaG_(f)^(@)` is NEGATIVE for roasting of sulphide ORE to oxide. Roasting of the sulphide to its oxide is thermodynamically feasible. Carbon and hydrogen are suitable reducing agents for metal SULPHIDES. Solution :Carbon and hydrogen are suitable reducing agents for metal sulphides.
