प्रश्न
Which of the following statements, about the advantage of roasting of sulphide ore before reduction is not true?
विकल्प
`Δ"G"_"f"^0` of sulphide is greater than those for CS2 and HS2.
`Δ"G"_"r"^0` 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.
उत्तर
Carbon and hydrogen are suitable reducing agents for metal sulphides.
Explanation:
Both C and H2 are not suitable for reducing sulphide are because `Δ"G"_"f"^0` of metal sulphide is more than that of CS2 and H2S which be formed as result of reduction.
