Question

It is possible for sodium to reduce aluminium oxide to aluminium at 298 K.
Given that $G_f^{0}of{Al}_2{O}_3$ $at$ $298K=-{1582kJmol}^{-1};G_f^{0}of{Na}_{2}O\left(s\right)at298K=-377kJ{mol}^{-1}$.
If true enter 1, else enter 0.

Answer 1

The reaction taking place is the following:

$A{l}_2{O}_3+6Na\to 3N{a}_{2}O+2Al$

$\Delta G_f^o$ for the reaction is $(3\times -377+1582)kJmo{l}^{-1}=$ $451kJmo{l}^{-1}$

Since, $\Delta G_f^o$ is positive, the above reaction is not feasible.

Hence, correct answer is $0$.
