Suggest a condition under which magnesium could reduce alumina.

Text Solution

Verified by Experts

The two equations are :
(1) `(4)/(3)Al+O_(2)rarr (2)/(3)Al_(2)O_(3),`
(2) `2Mg+O_(2)rarr 2MgO`
At the point of intersection of the `Al_(2)O_(3)` and `MgO` curves the `DeltaG^(@)` is zero for the reaction : `(2)/(3)Al_(2)O_(3)+2Mgrarr 2MgO+(4)/(3)Al`
Magnesium can reduce alumina below that point.
