Question:
For the ethanol(1)/chloroform(2) system at 50°C, the activity coefficients show interior extrema with respect to composition [see Fig. 13.4(e)].
(a) Prove that the van Laar equation cannot represent such behavior.
(b) The two-parameter Margules equation can represent this behavior, but only for particular ranges of the ratio A21∕A12. What are they?
