C. Thermodynamic Relationships Involving the Equilibrium Constant¹

¹ For the limitations and for further explanation of these relationships, see, for example, K. Denbigh, The Principles of Chemical Equilibrium, 3rd ed. (Cambridge: Cambridge University Press, 1971), p. 138.

For the gas-phase reaction

1. The true (dimensionless) equilibrium constant

RT lnK = –ΔG

where a_i is the activity of species i

where γ_i is the activity coefficient

K = True ...
