CHNOSZ: Thermodynamic Calculations for Geobiochemistry
Version 1.1.3

An integrated set of tools for thermodynamic calculations in geochemistry and compositional biology. Thermodynamic properties are taken from a database for minerals and inorganic and organic aqueous species including biomolecules, or from amino acid group additivity for proteins. High-temperature properties are calculated using the revised Helgeson-Kirkham-Flowers equations of state for aqueous species, and activity coefficients can be calculated for specified ionic strength. Functions are provided to define a system using basis species, automatically balance reactions, calculate the chemical affinities of formation reactions for selected species, calculate equilibrium activities, and plot the results on chemical activity diagrams.
