Textbook Question
Chapter 17, Problem 5ALQ
A friend tells you, “Free energy G and pressure P are related by the equation G = G° + RT ln(P). Also, G is related to the equilibrium constant K in that when Gproducts = Greactants，the system is at equilibrium. Therefore, it must be true that a system is at equilibrium when all the pressures are equal.” Do you agree with this friend? Explain.
