Problem 12.16: The data below are for a vapor/liquid system of two unnamed components:
a) Calculate the activity coefficients of the two components and plot them against x1 . Your graph should be done on the computer and it should be properly annotated.
b) Does this system exhibit positive or negative deviations from ideality?
c) Determine whether the system is best described by the Margules or the van Laar equation and determine the parameters of the corresponding equation.
