"NettetThe van der Waals equation is not as accurate as more modern cubic equations of state. However, as inspection of Equation (E7.2D) shows, it provides a simple relation between the fugacity coefficient and molecular parameters. For an ideal gas a=b=0 a = b = 0, so the fugacity coefficient is 1, as we expect. " - Integration of van der waals equation
