The following shows the VLE Data for the ethanol water system. Your assignment is to fit it to a range of activity coefficient equations, find the one that fits the data the best and then explain why you think that particular equation worked the best

After completing the fit, look for additional data for temperatures other than $343\mathrm{.}15K($at least $25$ degrees different$).$ Test the equation for the new set of data. Is the fit equally good? If not why. Suggest some remedies to make the activity coefficient equation work for different temperatures as well.
