Redlich–Kwong equation of state

Empirical algebraic equation of state more precise than the Van der Waals equation

In physics and thermodynamics, the Redlich–Kwong equation of state is an empirical algebraic equation that relates temperature, pressure, and volume of gases. It is generally more accurate than the van der Waals equation and the ideal gas equation at temperatures above the critical temperature. It was formulated by Otto Redlich and Joseph Neng Shun Kwong in 1949.
