Problem 1.
For mixing two components of a non-ideal solution together (A and B)
using a model 2-D square array, the expression for AG
is given in eqgn. 7.38.
mixing
(A) Derive the expression for the derivative of this expression with respect to XA (i.e.,
d(AGmeting)/ dx,).
(B) Using separate Excel plots, plot both AGg and d(AGing)/ dx, for xa = 0.100 to
0.900 in 0.025 increments at T = 298.15 K for three different values of Aɛ: 520, 620,
720 J/mole. Do not hand draw these plots but include copies of your actual Excel plots
in your answer.
(C) What do the plots for each value of Aɛ indicate regarding the solution behavior of A
mixing
and B?
