Dieterici equation of state: Difference between revisions

Revision as of 17:30, 6 February 2008

The Dieterici equation of state, proposed in 1899 (Ref. 1) is given by

\left.p(v-b)\right.=RTe^{-a/RTv}

where

a={\frac {4R^{2}T_{c}^{2}}{P_{c}e^{2}}}

and

b={\frac {RT_{c}}{P_{c}e^{2}}}

where $p$ is the pressure, $T$ is the temperature and $R$ is the molar gas constant. $T_{c}$ is the critical temperature and $P_{c}$ is the pressure at the critical point.
