Homework Help: Calculating Free Energy

  1. Apr 13, 2006 #1
    Calculate the gibbs free energy for a reaction which has a standard enthalpy = -196kJ/mol and standard entropy = 151 J/K mol at 32C.

    G = -196 KJ/MOL -[-305.15 K*0.15] = -242KJ

    Thank you.

    You're adding kiloJoules to Joules...

    No, I think he did not. Because he converted 151 J to 0.15 kJ:
