Extended Kohler Theory

Derivation of the Kohler equation is based on a combination of two expressions the Kelvin equation, which governs the increase in water vapor pressure over a curved surface and modified Raoult s law, which describes the water equilibrium over a flat solution

Kohler theory was originally developed for inorganic salt solutes and, as in Section 17.2.5, can be readily adapted to an insoluble substance as well. Recently Kohler theory has been extended to soluble trace gases, slightly soluble substances, and solutes that...
