Consider a mixture of iso-propanol and toluene. Use the UNIFAC method to find the activity coefficients. Then, create a ??? diagram and an ?? diagram of this system at ? = 101 ???.
Iso-proponol: A=16.6796, B=3640.2, C=219.61
Toulene: A=13.932, B=3056.96, C=217.625. These are the units of
Celsius and kPa. For the UNIFAC coefficients I have to use a
spreadsheet. Which coefficients do I send?
