Table-4 shows the relative deviation (RDX) for each experimental fusion enthalpy tested using the same data of activity coefficient
where A is alkalinity, a is activity, 0.94 is an empirical coefficient accounting for the contribution of carbonate alkalinity to the total alkalinity of soil solution [Alk.sub.[SIGMA]]; y' is the activity coefficient
of the singly charged particle (free ion or its associate); and y" is the activity coefficient
of the doubly charged particle (Minkina et al., 2012a).
Then, it discusses the proposed methodology for calculating fugacity and activity coefficients
in the selected binary samples, showing the main equations required for its determination.

The modified Clegg-Pitzer equations have been used to derive the activity coefficients
of different species present in the equilibrated liquid phase (Li and Mather, 1994; Kundu et al., 2003; Kundu and Bandyopadhyay, 2005).
The activity coefficients
and other thermodynamic properties of hydrochloric acid are dependent not upon the value of E[degrees] but on the difference E-E[degrees].

Calculations concerning solubilities based on solubility products, effects of common ions and pH, and the calculation of activity coefficients
are presented in chapters 3 and 6.
In this study, IGC was successfully applied to determine certain thermodynamic and pyhsical properties of poly(ABM), poly(ABM0.41-co-AN) and poly(ABM0.71-co-AN), such as the glass transition temperature, Tg; the sorption enthalpy, IH 1S, sorption free energy, IG 1S; sorption entropy, IS 1S; the weight fraction activity coefficients
, a| 1a; partial molar free energy of mixing, IG 1a; partial molar heat of mixing, IH 1a; and the Flory-Huggins interaction parameters, I 12a, at infinite dilution.
Finally, limiting activity coefficients
of benzene and alcohols in swelled LDPE calculated from constants in Table 2 were compared with values estimated from the modified UNIFAC [43, 53] assuming that the solvent is a hypothetical liquid hydrocarbon that has the same density as LDPE.
