Carbon cannot reduce `Fe_(2)O_(3)` to Fe at a temperature below 983 K because

free energy change for the formation of CO is more negative than that of `Fe_(2)O_(3)`

CO is thermodynamically more stable than `FeO_(3)`

carbon has higher affinity towards oxygen than iron

iron has higher affinity towards oxygen than carbon
