ABSTRACT
The properties of a multicomponent phase depend, in general, on pressure, temperature, and mole fractions of all the components. For example, the fugacity of component i is
f f p T x x xi i c ( , , , , , )1 2 1… (17.1)
The fugacity of a pure component i at the pressure and temperature of the multi component phase is denoted by fio. It is a function of p and T only.
