A number of different “heats of adsorption” measured in flow calorimetric experiments are related to one another, to other common measurements of heat of adsorption, and to the theoretical surface enthalpy. Theoretical equations have been develop

The thermodynamics for the adsorption of a binary liquid mixture onto a solid is developed in order to establish the connections between the excess enthalpy and heats of mixing from immersion and frontal analysis experiments. Bulk heat of mixing data

The following features of the theory of van der Waals and of Cahn and Hilliard are proven to be true: It is possible to find a local free energy, ψi, depending upon T and the density profile, that sums (over i) to give the total free energy of the s

The thermodynamic theory of the adsorption of liquid mixtures onto solids is reviewed in order to compare essential differences between monolayer and non-monolayer theories. This leads to the development of a method for constructing non-monolayer the

The Bethe or quasichemical approximation, is applied to the two‐dimensional, triangular lattice gas in order to compute the probability of liquid drop formation in a supersaturated vapor. Comparison is made with the classical theory of homogeneous

The matrix method of statistical mechanics has been used to obtain an approximate adsorption isotherm for a lattice gas in the presence of a wall which interacts with adjoining sites. The excess number adsorbed per surface site has the form [ρII(z

The exact finite method, developed largely by Runnels, is modified so that calculations can be made of the properties of a single phase in equilibrium with other phases. The modification also allows the calculation of some boundary properties. Applic

A monolayer of adsorption is used to interpret the adsorption onto silica gel of ternary solutions containing n-heptane, toluene, and methanol. The model takes into account the non-ideality of the bulk liquid using previously-evaluated Wilson paramet

Tubers of Russet Burbank potatoes were stored at 36 F (2.2 C), 42 F (5.6 C), 45 F (7.2 C), 48 F (8:9 C), and 70 F (21.1 C) and respiration rates determined. Chemical treatments 4 with growth regulators were made and respiration rates determined on in

A general expression for the surface tension of a lattice gas is derived. The equation is γA / kT = 〈η〉g − 〈η〉1, where γ is the surface tension, A is the surface area, η is related to the eigenvector corresponding to the gas phase, and
