Clausius equation of state

The Clausius equation of state is given by

$\left[p+{\frac {a}{T(v+c)^{2}}}\right](v-b)=RT$

where

$a=v_{c}-{\frac {RT_{c}}{4P_{c}}}$

$b={\frac {3RT_{c}}{8P_{c}}}-v_{c}$

and

$c={\frac {27R^{2}T_{c}^{2}}{64P_{c}}}$

where $p$ is the pressure, $T$ is the temperature, $v$ is the volume per mol, and $R$ is the molar gas constant.
