functionlogFugacityCoefficient_pTN
Natural logarithm of fugacity coefficients
Information
The natural logarithmic fugacity coefficient arises frequently in thermodynamic expressions. According to [1], "unlike the fugacity itself this quantity is also well- defined at zero concentration of a a compound and the logarithmic form allows a wider range of numerical values to be represented".
