Vedclass · Answer

(B) According to the Ellingham diagram,the line for the formation of $Al_2O_3$ intersects the line for the formation of $MgO$ at approximately $1350^{\circ}C$. Above $1350^{\circ}C$,the standard Gibbs free energy of formation of $Al_2O_3$ is more negative than that of $MgO$. Therefore,$Al$ can reduce $MgO$ to $Mg$ at temperatures above $1350^{\circ}C$.

Predict conditions under which $Al$ might be expected to reduce $MgO$.
