Summary
Many minerals in the geochemical environment do not react rapidly enough with coexisting fluids to maintain thermodynamic equilibrium. Kinetic laws for this reason are required to predict the rates at which such minerals dissolve and precipitate. This chapter shows how rate laws of this class can be incorporated in multicomponent chemical reaction models, illustrates how such models behave, and provides advice on how the models might be best applied to advantage by scientists and engineers.
