Problem

Determine whether or not, it is possible for sodium to reduce aluminium oxide to aluminium at 298 K. Also calculate equilibrium constant. Given that Gf∘G_f^\circ of Al2O3\text{Al}_2\text{O}_3 at 298 K = −1582 kJ mol−1-1582 \text{ kJ mol}^{-1} ; Gf∘G_f^\circ of Na2O(s)\text{Na}_2\text{O}(s) at 298 K = −377 kJ mol−1-377 \text{ kJ mol}^{-1} .
