Question

How would we prepare metallic sodium and gaseous chlorine from sodium chloride?

Answer 1

HI,

In other words you want to do the reverse of the Born Haber cycle.

Explanation:

In the Born Haber cycle, the energetics of the formation of ionic salts are exhaustively measured and estimated. Formation of salt is thermodynamically downhill. In principle, Na+ could be reduced down to sodium metal; it would take a lot of energy and bother. Cl− anion could be oxidized up to Cl2(g) rather more easily.

HOPE IT HELPS!!!
