If nonideal solution behavior originates only from spatial and/or physical considerations among the solvents, nonideal solution activity coefficient
models will adequately account for excess swelling observed in elastomers.
Table-5: (a) Weight fraction activity coefficient
a|1a of with alcohols and alkanes systems for poly (ABM).
The authors demonstrated that the activity coefficient
of carbon dioxide is considerably higher in the methanol-carbon dioxide mixture, and that the non-linearity of the liquid phase is due to the auto association present in methanol (as they suggested).
The relation between the mass-based infinite dilution activity coefficient
of the solvent, ([[OMEGA].
Modification of PSRK mixing rules and results for vapor-liquid equilibria, enthalpy of mixing and activity coefficients
at infinite dilution.
in the liquid phase are very low compared to the other species present in the equilibrated liquid phase, they have been neglected in the material balances and activity coefficient
Influence of base (nickel and iron) and impurity elements in ferronickel on activity coefficient
and, as a result, on sulfur activity may be estimated by parameters of interaction of first order (the Wagner parameter), which represent ratio of partial derivative of logarithm of activity coefficient
of an element (in this case sulfur) to weight share (%) of the impurity
Neither the electromotive force nor the activity coefficient
was smoothed with respect to temperature.
16], because of the change of ion environment, the change of activity coefficient
and liquid junction potential error could modify the ion data as Na[HCO.
Ki is the equilibrium constant for the gas reaction and fi is the activity coefficient
16 Comparison and analysis of investment activity coefficient
and rate of return on investment in Industry
The weight fraction activity coefficient
(1) of the solute at infinite dilution can be calculated from following relation .
