Calculate the activity coeffi cients of a binary mixture of 41.5 mol% ethanol (1) in benzene (2)

Question:

Calculate the activity coeffi cients of a binary mixture of 41.5 mol% ethanol (1) in benzene (2) at 45°C using the UNIQUAC activity coeffi cient model. The UNIQUAC parameters are reported as follows:image text in transcribed

The system pressure under these conditions has been reported to be 309.59 torr and a mole fraction of ethanol in the vapor of 0.3842. How do your calculated activity coeffi cients compare to the experimental data?
