iron has higher affinity towards oxygen than carbon

Vedclass · Answer

(D) According to the Ellingham diagram,the line for the formation of $Fe_2O_3$ lies below the line for the formation of $CO$ at temperatures below $983 \ K$. This indicates that the formation of $Fe_2O_3$ is more spontaneous (more negative $\Delta G^\circ$) than the formation of $CO$ in this temperature range. Therefore,iron has a higher affinity for oxygen than carbon below $983 \ K$,making the reduction of $Fe_2O_3$ by carbon non-spontaneous.

Carbon cannot reduce $Fe_2O_3$ to $Fe$ at a temperature below $983 \ K$ because
