✦ Synopsis

Convenient and accurate methods of calculating the thermodynamic properties of gases from experimental compressibility-factor data through the use of the Redlich and Kwong equation of state are presented. Analytical and graphical methods are combined. As an example, fugacity and activity coefficients are calculated for the nitrogen-ethylene system at 50°C. for pressures up to 500 atm.
