At the temperature corresponding to which of the points in Fig, FeO will be reduced to Fe by coupling the reaction 2FeO → 2Fe + O2 with all of the following reactions?
(a) C + O2→ CO2
(b) 2C + O2→ 2CO and
(c) 2CO + O2→2 CO2
At point B and E the ∆G values for (a),(b) and (c) is lesser than that for reduction of FeO to Fe which means that the total ∆G for the reaction will be large and negative and the reaction will take place.
