Calculation of the standard molal thermodynamic properties and chemical
affinities of reactions between and among minerals, inorganic, organic,
and/or biomolecular aqueous and crystalline species. Incorporation of an
extensive database of thermodynamic properties of species and algorithms
for computing the standard thermodynamic properties of neutral and ionized
proteins from amino acid group contributions. Generation of chemical
speciation and predominance diagrams for stable and metastable equilibrium
in open systems as a function of temperature, pressure, and chemical
activities or fugacities of basis
species.
