Given below are two statements:
| I: | The Ellingham diagram provides an idea about the feasibility of a reaction. |
| II: | The Ellingham diagram explains the rate of the reduction reactions. |
In light of the above statements, choose the most appropriate answer from the options given below:
| 1. | I is correct and II is incorrect. |
| 2. | I is incorrect and II is correct. |
| 3. | Both I and II are correct. |
| 4. | Both I and II are incorrect. |
Considering Ellingham diagram, which of the following metals can be used to reduce alumina?
1. Fe
2. Zn
3. Mg
4. Cu
| 1. | Carbon and hydrogen act as suitable reducing agents for metal sulphides |
| 2. | The \(\Delta_f G^0\) of the sulphide is greater than those for \(C S_2\) and \(\mathrm{H}_2 \mathrm{~S}\) |
| 3. | The \(\Delta_f G^0\) is negative for roasting of sulphur ore to oxide. |
| 4. | Roasting of the sulphide to the oxide is thermodynamically feasible |
