Adsorption The separation achieved depends in part on the selectivity of adsorption at the bubble surface. At equihbrium, the adsorption of dissolved material follows the Gibbs equation (Gibbs, Collected Works, Longmans Green, New York, 1928).

These authors also investigated 2-norbornyl lithium and found a protodelithiation enthalpy of —222 5 kJmoP. They asserted that the norbomyl lithium was present in an exo/endo ratio of essentially 1 1. Equating Gibbs energy and enthalpy differences vida infra), we will assume there is a negligible difference between the enthalpies of formation of the isomeric norbomyl lithiums. From equation 10 with n-butyl lithium as... 

It is also important to understand that all these properties obey all the rules of calculus. As a consequence these properties are related through fundamental equations, Maxwell equations, Gibbs-Helmholtz equations, and Gibbs-Duhem equations.

In geological surfaces, the solid-gas and solid-liquid interfaces are important, so the correct thermodynamic adsorption equation (Gibbs isotherm) cannot be used. Instead, other adsorption equations are applied, some of them containing thermodynamic approaches, and others being empirical or semiempirical. One of the most widespread isotherms is the Langmuir equation, which was derived for the adsorption of gas molecules on planar surfaces (Langmuir 1918). It has four basic assumptions for adsorption (Fowler 1935) ...

Chemical thermodynamics was developed by Pierre Maurice Martin Duhem (Paris, lo June i86i-Cabrespine, 14 September 1916), professor of theoretical physics in Bordeaux, who published on the equations for heats of solution and dilution which had been deduced by Kirchhoff, on the liquefaction of gaseous mixtures, eutectic and transition points for binary mixtures which can form mixed crystals, and a long series of papers on false equilibrium of doubtful value. He published some books on thermodynamics and later on the history of science. An important general thermodynamic equation (Gibbs-Duhem equation) was deduced independently by Gibbs and Duhem. ... 

Combining Eqs. (11.14) to (11.16) with Young s equation, Gibbs arrived at the following equation for the adhesion tension,...
