Chapter 10, Problem 10.41P

(a)

Interpretation Introduction

Interpretation:

Determination of expression of partial molar excess properties $\overline{M_1^E}$ and $\overline{M_2^E}$

Concept introduction:

Excess properties are defined a the difference between the actual property value of a solution and the value it would have as an ideal solution at the same temperature, pressure and composition.

The formula for the partial molar excess properties are:

  $\begin{array}{l}\overline{M_1^E}=M^E+\left(1-x_1\right)\frac{d{M}^E}{d{x}_1}\\ \overline{M_2^E}=M^E-\left(x_1\right)\frac{d{M}^E}{d{x}_1}\end{array}$
