Regress the binary interaction parameters of the UNIQUAC model to best describe the isobaric VLE data measured by Kojima et al. at 1 atm and listed below. As objective function, use:

a) relative quadratic deviation in the activity coefficients

b) quadratic deviation in boiling temperature

c) relative quadratic deviation in vapor phase composition

d) relative deviation in separation factor

Adjust the vapor pressure curves using a constant factor to exactly match the author's pure component vapor pressures.
