Al2O3 ---> Delta G fusion -1582.3

HCl----> -131.2

AlCl3 -----628.8

H2O --- -237.1

The equation is Al2O3 + 6HCl ---> 2 AlCl3 + 3H2O

products - reactants?

[2(-628.8)+3(-237.1) - (-1582.3)+6(-131.2) =-1178.8 KJ

But the answer is supposed to be +400.6 KJ/mol

**DrBob222**, Wednesday, May 1, 2013 at 10:15pmIf you do the math right you get 400.6 kJ/mol. At least that's what I obtained.
