Use the data in the table to calculate the Delta G0 of the following reaction at 298k:

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

  • Chemistry - ,

    If you do the math right you get 400.6 kJ/mol. At least that's what I obtained.
