Answer:

Magnesium can reduce aluminium oxide and aluminium can also reduce magnesium oxide.Aluminium can reduce magnesium oxide at a temperature of about 2000 K because in this temperature range the line of ΔG° (Mg, MgO) lies above the line of ΔG° (Al,Al2O3) in the Ellingham diagram. Therefore, under these condition ΔrG° for reduction of MgO with Al will be negative and hence the reaction would be feasible.

Answer:

Above 1350°C, the standard Gibbs free energy of formation of Al2O3 from Al is less than that of MgO from Mg. Therefore, above 1350°C, Al can reduce MgO.
