Pressure correction factor accounts for intermolecular forces.

$\left(\text{P}+\frac{\text{na}}{{\text{v}}_{\text{m}}^2}\right)\left({\text{v}}_{\text{m}}-\text{nb}\right)=\text{nRT}$

if n = 1$\left(\text{P}+\frac{\text{a}}{{\text{v}}_{\text{m}}^{\text{2}}}\right)$is responsible for intermolecular forces
