Calculating Free Energy: Standard Enthalpy and Entropy at 32C

[Soaring Crane]

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.

G = H - TS

Isn't that what I did?

You're adding kiloJoules to Joules...

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

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

Oops didn't notice that.
