I need to figure out Delta H, Delta S, and Delta G for the following problem.

Question

H2+F2 Yeilds 2HF the temperature is at 298K

Answer 1

You find delta Hf in a table in the back of your text.
delta Hrxn = (n*DHproducts)-(n*DHreactants)
Delta S is done the same way.
Delta Go usually is available in the same table. Or
DG = DH-TDS.
