Question

In which condition aluminium might be expected to reduce magnesia

Answer 1

Explanation:

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
