The following are four liquid-vapor phase diagrams: ethanol-toluene at 65°C (top left), furan-carbon tetrachloride at 30°C (top right), methane-n-butane at 37.8°C (bottom left) and n-pentane-methanol to 15 bar (bottom right). Choose a VLE model that you think is the most appropriate for the VLE calculation of each binary mixture. n-Pentane-Methane Time DADA 05 05 10 The VLE models that can be selected are given in the following table. Give your reasons for each choice. Table 1. Thermodynamic property models available in a simulator.
