Comments on the coordination number models and equations of state of Tsai and Chen [Fluid Phase Equilibria 187–188 (2001) 39–59 and 232 (2005) 100–112]

This paper notes typographical errors in the coordination number model of Tsai and Chen [Fluid Phase Equilib. 232 (2005) 100–112] for square-well mixtures and in the equations of state of Tsai and Chen [Fluid Phase Equilib. 187–188 (2001) 39–59; Fluid Phase Equilib. 232 (2005) 100–112] for pure square-well fluids and their mixtures. In addition, the divergence condition and applicable range of the coordination number model of Tsai and Chen (2005) for mixtures are described.
