Abstract

At the critical point one has \(\left( \partial p/\partial V_M\right) _T =0\) and \(\left( \partial ^2 p/\partial V_M^2\right) _T=0\). By calculating the derivative of the van der Waals equation with respect to \(V_M\), we find that the first condition reads \(p_c-a/V_{Mc}^2+2ab/V_{Mc}^3=0\).
