Calculate ∆G0 for the following reaction.
4XY + 3Z2−→2Z3X2+ 2Y2
Substance ∆H0f S0kJ/mol J/mol·K
XY 205.0 75.0

I would do the following:
Calculate dGo for each substance by dGo - dHo - TdS. Use 298 for T and REMEMBER S is in J/mol and dH is in kJ/mol.

Then dGorxn = (n*dGo products) - (n*dGo products)
