31. It is important to recognize that the equilibrium constant K is independent on both ? and g. 32. The relation between the Gibbs free energy and the equilibrium constant can be found by considering chemical potentials. 33. The "'binding constant "'is a special case of the equilibrium constant K. 34. Note that the free reactant concentrations can be regarded as implicit parameters in the equilibrium constant refinement process. 35. The equilibrium constant that describes this equilibrium, K, is presumably independent on the catalytic chemical reaction. 36. The strength of a weak acid is represented as either an equilibrium constant or as a percent dissociation. 37. The equilibrium constant for this dissociation can be predicted by the change in Gibbs free energy of this reaction. 38. In a condensed phase, the pressure dependence of the equilibrium constant is associated with the reaction molar volume. 39. For example, the equilibrium constant for the formation of acetone hydrate from acetone is only 0.002. 40. Because of this the Pitzer equations provide for more precise modelling of mean activity coefficient data and equilibrium constants .
