The temperature at which carbon reduce FeO to Fe and produce CO is:
1. Lower than 400 oC
2. 400 oC
3. Higher than 600 oC
4. Higher than 400 oC
The correct statement among the following regarding the reaction of FeO below point A in the above diagram is:
1. Reduced by carbon monoxide only.
2. Reduced by both carbon monoxide and carbon.
3. Reduced by carbon only.
4. Not reduced by both carbon and carbon monoxide.
The correct statement for the reduction of FeO at the temperature corresponding to point D is:
| 1. | ∆G value for the overall reduction reaction with carbon monoxide is zero. |
| 2. | ∆G value for the overall reduction reaction with a mixture of 1 mol carbon, and 1 mol oxygen is positive. |
| 3. | ∆G value for the overall reduction reaction with a mixture of 2 mol of carbon, and 1 mol of oxygen will be positive. |
| 4. | ∆G value for the overall reduction reaction with carbon monoxide is negative. |
Consider the following figure
At the temperature corresponding to which of the points FeO will be reduced to Fe by coupling the reaction 2FeO →2Fe + O2 with all of the following reactions?
(i) C + O2 →CO2
(ii) 2C + O2 → 2CO
(ii) 2CO + O2 → 2CO2
a. Point A
b. Point B
c. Point D
d. Point E
