Homework 4 Thermo ll Fall 2010 Numbered problems from Sandler, 4 th edition. Due: Oct 7, 2010 in class. 1. Getting lost in variable meanings and the chain rule is one hurdle that obstructs the understanding of ideas that are not really that exotic. So to deal with this, show all the steps in obtaining Eq. 8.6.2 from 8.6.1. 2. Show that the partial molar volume data in Table 8.6 2 follows the Gibbs Duhem Relationship. Use numbers where three different compositions are tested that fall over the mole fraction range . 3. Problem 8.20. Find only the partial molar volumes (i.e. do not do part b). You do not have to do all the compositions, but span the composition range by obtaining 3 or 4 values.

Alternate Numerical Solution to Problem 8.20 Here, I start with the above, which is the data converted from that given. The converted data is found in the solution that the author provides. How to convert the data in the problem statement to the above table was discussed in class. As an example, let’s do calculations at ~72 weight percent alcohol, which means that we have 0.5 mole fraction of
