Answer to Question #1336 in Physical Chemistry for Ted Mole

Question

What is the difference between ΔG and delta ΔG˚/ΔG˚’ in thermodynamics? Looking at my textbook they both seem to mean the same thing - the change in free energy.

Answer 1

ΔG& is the change in Gibbs free energy, ΔG˚ may be it's a standard change of reaction in Gibbs free energy, ΔG˚’ - seems to be a& change of reaction in Gibbs free energy.
G and G˚ are related in such way:
G = G˚ + N kT ln(p/p˚)
