Problem 2
The Gibbs energy of mixing for the binary mixture of A and B are given below as a function of
mol fraction of A at a given T and P. At the same condition, some amounts of liquid A and liquid
B are mixed and brought to equilibrium. For each of the cases below, determine how many
phases are formed, and for each phase, determine the amount of that phase (in mol) and the
composition of the phase (in mol% A).
a) Mixing 90 mol of A and 10 mol of B
b) Mixing 60 mol of A and 40 mol of B
c) Mixing 50 mol of A and 50 mol of B
