A Graphical Representation for the Fugacity of a Pure Substance
Book, Neil L.; Sitton, Oliver C.
Chemical Engineering Education, v44 n3 p208-212 Sum 2010
The thermodynamic equations used to define and compute the fugacity of a pure substance are depicted as processes on a semi-logarithmic plot of pressure vs. molar Gibbs energy (PG diagram) with isotherms for the substance behaving as an ideal gas superimposed. The PG diagram clearly demonstrates the physical basis for the definitions and the methods for computing the value of the fugacity of a pure substance.
