  • For the reduction of FeO at the temperature corresponding to point D, which of the following statements is correct? (i) Delta G value for the overall reduction reaction with carbon monoxide is zero.

For the reduction of \text {FeO} at the temperature corresponding to point D, which of the following statements is correct?

(i) \Delta \text {G} value for the overall reduction reaction with carbon monoxide is zero.

(ii) \Delta \text {G} value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is positive.

(iii) \Delta \text {G} value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be positive.

(iv) \Delta \text {G} value for the overall reduction reaction with carbon monoxide is negative.

Answers (1)

The answer is the option (i). At point D, the curves of oxidation of iron and oxidation of \text {CO} intersect each other.

Thus, \Delta \text {G}^{0} for the reaction \text {FeO+CO}\rightarrow \text {Fe+CO}_{2} is zero.

                                              \text {2FeO+O}_{2}\rightarrow \text {2FeO};\Delta \text {G}^{0}=-280

                                              \text {2CO+O}_{2}\rightarrow \text {2CO};\Delta \text {G}^{0}=-280

                                       Resulting in \text {2FeO+2CO}_{2}\rightarrow \text {2Fe+2CO}_{2}

                                           \Delta \text {G}^{0}= (-280+280)=0
