Question:

The volume of a binary mixture has been reported in the following polynomial form: 

n V(T, P, x, x2) = xb + x2b + x1x2 ; (x - x) i=0

a. What values should be used for b1 and b2?

b. Derive, from the equation here, expressions for V̅1,

V2, Vex = V - V and Vex = V  V. 1 1 1 2 2

c. Derive, from the equation here, expressions for the partial molar excess volumes of each species at infinite dilution, that is, V̅ex1 (T, P, x1 → 0) and V̅ex2 (T, P, x2 → 0).
