Cubical Equation of State (EOS)
 Based on the accuracy of measurment, according to the
corrections made by different researchers we have
several cubical equation of states

Theorem of corresponding states
Three Parameter
 Corresponding states correlation of Z based on this theorem
are called two parameter correlation, because they require use
of the two reducing parameter Tr and Pr
...

 Appreciable improvement results form introduction of a third
corresponding state parameter (in addition to Tr and Pr),
characteristic of molecular structure; the most popular such
parameter is the acentric factor ω, introduced by K

...
7 for the reduced
temperature Tr of the typical simple
fluids (argon,krypton, xenon) the
logarithm of Reduced pressure is (–1)

This is indicative of lower volatility of
the substance, which suggests
relatively stronger intermolecular
interactions in the
condensed phase
“The compressibility factor for all fluids
with the same value of ω, when
compared at the same reduced
temperature and pressure are
approximately the same, and hence the
deviation from ideal-gas behavior is
nearly the same
