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

NCERT Exemplar Solutions of Class 12 Chemistry Chapter 6 General Principles and Processes of Isolation of Elements-1

(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

 

Correct Answer: (i) ∆G value for the overall reduction reaction with carbon monoxide is zero

Explanation: For the reduction of FeO at the temperature corresponding to point D,

  1.  ∆G value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is negative.
  2.  ∆G value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be negative.
  3.  ∆G value for the overall reduction reaction with carbon monoxide is positive.
