Using the mixture and equilibrium conditions from problem 1: 1) Calculate equilibrium ratios (K-values) by using Wilson's correlation. 2) How many phase(s) is(are) present for the mixture of the system given? (Select one) a) One phase OR b) Two phases 3) If two phases are present, what would be the composition of equilibrium vapor (yi?) and the composition of equilibrium liquid (xi?) ? If one phase is present, what would be the composition of that phase?
