Aluminum is one of the most versatile metals. It is produced by the Hall-Heroult process, in which molten cryolite, Na3AlF6, is used as a solvent for the aluminum ore. Cryolite undergoes very slight decomposition with heat to produce a tiny amount of F2, which escapes into the atmosphere above the solvent. Kc is 2 10-104 at 1300 K for the reaction. Na3AlF6(l) 3 Na(l) Al(l) 3 F2(g) What is the concentration of F2 over a bath of molten cryolite at this temperature

Explanation:

The equation for this process can be given as:

Also given that:

If we construct an ICE Table; we have:

Initial               -                           -                  -              0  

Change           -                           -                  -             +x

Equilibrium      -                           -                  -             x

In equilibrium constant, liquids are not involved; as such:
