Vedclass · Answer

(B) According to the Ellingham diagram,the line for the formation of $CO_2$ from $C$ and $O_2$ intersects the line for the formation of $Fe_2O_3$ from $Fe$ and $O_2$ at approximately $983 \ K$. Above $983 \ K$,the Gibbs free energy change $(\Delta G)$ for the formation of $CO_2$ becomes more negative than the $\Delta G$ for the formation of $Fe_2O_3$. This implies that at temperatures above $983 \ K$,carbon has a higher affinity for oxygen than iron does,allowing carbon to effectively reduce ferric oxide to metallic iron.

Carbon can reduce ferric oxide to iron at a temperature above $983 \ K$ because
