Which of the following faction is of no significance for roasting sulphide ores to the oxide and not subjecting the sulphide ores in carbon reduction directly ?

Options

A. Metal sulphides are less stable thasn the corresponding oxide
B. `CO_(2)` is thermodlynamically more stable than `CS_(2)`
C. `CO_(2)` is more volatile than `CS_(2)`
D. Metal suphides are thermodynamically more stable than `CS_(2)`

Answer

c

Explanation

The reduction process is based on the thermodystanic stabillty of the process but not on their volectility
