Question

Carbon can reduce ferric oxide to iron at a temperature above 983 K because, carbon monoxide formed is thermodynamically less stable than ferric oxide, carbon has a higher affinity towards oxidation than iron, free energy change for the formation of carbon dioxide is less negative than that for ferric oxide, iron has a higher affinity towards oxygen than carbon

MARKS App · Accepted Answer

Above 983 K , free energy change for the formation of CO 2 ​ is more negative than that for ferric oxide. Thus, above this temperature, carbon has a higher affinity towards oxidation than iron.
