2.8. The following is a set of activity-coefficient data for a binary liquid system as determined from VLE data: Inspection of these experimental values suggests that they are noisy, but the question is whether they are consistent, and therefore possibly on average correct. (a) Find experimental, values for GE/RT and plot them along with the experimental values of ln1 and ln2 on a single graph. (b) Develop a valid correlation for the composition dependence of GE/RT and show lines on the graph of part (a) that represent this correlation for all three of the quantities plotted there. (c) Apply the consistency test described in Ex. 12.1 to these data, and draw a conclusion with respect to this test
