Isochoric model - I

There are 4 Excel files with the partial molar Gibbs energies (G2) of ions at the saturated water vapor pressure, P = 100 MPa and P = 500 MPa, and the ionization constants in water for CO2, H2S and NH3 at different temperatures and pressures, calculated within "isochoric" model. On March 19, 2025 the Mathematica files and their pdf copies were added, showing all data necessary to calculate the thermodynamic properties of NH3(aq), NH4+, H2O, OH- at 873 K and various pressures, as well as pK for reaction NH3(aq) +H2O = NH4+ + OH- at the same conditions.
