Activity Coefficient Model: Redlich-Kister

The model is described in: O. Redlich, A.T. Kister, Ind. Eng. Chem. , 1948, 40, 341.

GEX/(R ×T) = Σai ×x1 ×x2 ×(x1 - x2)i, where the summation is from i = 0 to nTerms.

Parameters determined in TDE are the a vector.

Temperature dependencies for activity-coefficient model parameters are expressed with: TDE-TSeries1.

annotated equation parameters window: under constants is given number of terms. Under parameters is given table of parameters A_n and B_n, which are used to construct a_n using the expression a_n=A_n+(B_n / T), where T is temperature in Kelvin

Details of the model implementation in TDE, including ThermoML-Equation representation are available. (See the ThermoML web site for details of this IUPAC communication standard.)
