An Improved Model for Calculating Heats of Dilution and Equilibrium Constants for High Temperature Aqueous Electrolyte Solutions
… is sufficiently large that the association equilibrium must be incorporated in any model describing the solutions. These association reactions usually do not occur to a measurable extent at room temperature. Oscarson and co-workers have designed a correlation model based on the excess Gibbs …

Cooperativity of ligand binding as a function of monomer-dimer equilibrium Parameters and Acceptor Concentration
<p>A general monomer-dimer equilibrium system involving ligand interactions is presented. Cooperativity features of specific limited models are analyzed by selecting the appropriate family of equilibrium constants from this general scheme. Each system is then characterized in terms of Hill …

On the phase behavior and particle formation in polyimide/solvent/nonsolvent ternary systems
… ternary systems were studied. A quantitative equilibrium approach was considered in the B-bonding studies of these ternary systems. The effect of H-bonding on the physical properties and phase behavior of the ternary systems was investigated. The critical requirements for the control of …

The Partial Pressure of Hydrogen Chloride from its Solutions in Non-Aqueous Solvents at 25° C. III. Ethylene Glycol Solutions
… Henry's law. Also a method of calculating the equilibrium constants of hydrogen chloride in such solvents was devised. |Since then, Zellhoefer and coworkers have made an extensive study of the solubility of halogenated hydrocarbons (e.g. CHC12F and types such as CH3X, CH2X2, CHX2, CH4, C2X6) in …

Ab initio determination of kinetics for atomic layer deposition modeling
… partition functions from statistical mechanics, equilibrium constants and reaction rates can be calculated. Several tools were created in Python to aid in the calculation of these quantities, and this procedure was applied to two systems- zinc oxide deposition from diethyl zinc (DEZ) and water, …

The Formal Redox Potential of the Permanganatemanganous System in Sulfuric Acid
Equilibrium constants of redox reactions, tho degree of completeness of respective reactions, activity coefficients of solutes, choice of reducing or oxidising agents to be used—those and many other problems in analytical chemistry can be calculated or predicted satisfactorily through a knowledge …

Modelling the optical, kinetic, and thermodynamic properties of soot precursor molecules
… bay closure processes is also studied. The rate constants determined for the pathways are then used in kinetic simulations in 0D homogeneous reactors. The hydrogen abstraction based pathway is seen to dominate until higher temperatures, where the carbene pathway takes over. The results suggest …

Adsorption from binary solutions of polar n-decyl derivatives and heptane onto alumina
… ≃ ethyl octanoate. However, adsorption equilibrium constants calculated for each system indicate that the order of preferential adsorption is ethyl octanoate > n-decanol > n-decylamine > n-decanoic acid. An explanation for the discrepancy is put forth. A theoretical model of surface …

Pourbaix diagrams at elevated temperatures: a study of Zn and Sn
… spectroscopic techniques, were used to calculate equilibrium constants and the Gibbs energies of Sn complexes for E-pH diagram construction. The SnOH3+ and Sn(OH) species were incorporated, for the first time, into the 298.15 K and 358.15 K diagrams, with novel G ͦ values determined at 358.15 K.

Estimation method for the thermochemical properties of polycyclic aromatic molecules
… consistency requires that reverse rate constants be calculated from the forward rate constants and from the equilibrium constants. The later are obtained from the thermochemical properties of reactants and products. The predictive ability of current kinetic models is significantly …

Extraction study of cadmium (II) and copper (II) using Aliquat 336
… stoichiometry of the extracted complexes and the equilibrium constants of extraction reactions. In the membrane extraction study, extraction rates and capacities of the membrane were studied as functions of major variables such as the concentration of Aliquat 336 in the membrane and the thickness …
