Predict conditions under which Al might be expected to reduce MgO

Explanation

Al can reduce magnesium oxide at a temperature above 1600K because at this temperature the Line of
.Al_2 O_3. ) in the Ellingham diagram. Hence under these conditions, .G^0. for reduction of .MgO. with .Al. will be negative and hence the reaction. .3 MgO+2 Al rarr 3 Mg+Al_2 O_3. would be feasible.
