Question:
For the reduction of FeO at the temperature corresponding to point D, which
of the following statements is correct?
(i) ∆G value for the overall reduction reaction with carbon monoxide is
zero.
(ii) ∆G value for the overall reduction reaction with a mixture of 1 mol carbon
and 1 mol oxygen is positive.
(iii) ∆G value for the overall reduction reaction with a mixture of 2 mol carbon
and 1 mol oxygen will be positive.
(iv) ∆G value for the overall reduction reaction with carbon monoxide is
negative.
Solution:
Option (i) is the answer.
