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 + O22 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.
