# Difference between revisions of "Dieterici equation of state"

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

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

where

$a = \frac{4R^2T_c^2}{P_ce^2}$

and

$b=\frac{RT_c}{P_ce^2}$

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.
