Hover over the names of minerals or species to show the chemical formulas. Click on the names to look up publications reporting the thermodynamic data (* indicates a second reference), or click on the point symbols to see examples of papers using related equilibrium calculations.
The y-axis here is labeled log K (as in e.g. Shock, 1993). Because each of the reactions is written to produce 1 mole of H2O, the log K value is equal to the theoretical logarithm of activity of H2O (water activity) at equilibrium.
