Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Relationships between CO2, thermodynamic limits on silicate weathering, and the strength of the silicate weathering feedback (2018), Earth and Planetary Science Letters. Implementations in other papers (listed below) may differ.

1. Develop theoretical framework
   Derive mathematical relationships for CO2 dependence of equilibrium solute concentrations based on equilibrium constants and reaction stoichiometry. Express equilibrium constant K in terms of equilibrium activities of reactants and products for the general weathering reaction: mM + 2CO2(g) + H2O ↔ sS + 2HCO3- + aA + bB + cSiO2(aq).
