Comments re Chapter 7 Problems:
|
7-13 |
A basic problem involving the vaporization equilibrium of water. |
|
7-16 |
A simple thought problem that requires a little knowledge of chemistry. The quantities DvapHo and DvapUo measure the strength of intermolecular attractions in the liquid (i.e., in a condensed) phase. |
|
7-21 |
Short, but very important T/F problem. |
|
7-22 |
Calculate the vapor pressure of an organic liquid given the normal boiling point and DvapHo at the normal boiling point using the Clausius-Clapeyron equation. |
|
7-23 |
Standard problem: Estimate the pressure that must be applied to lower the melting point of water n deg C. |
|
7-43 |
A small thought problem designed to help with understanding of chemical potential. |
|

7-2 |
A problem in which the Gibbs phase rule must be used to determine the number of degrees of freedom. The key is correctly counting phases (easier) and components (harder). This problem has no complications; the problem is straightforward. |
|
7-4 |
Another problem based on the Gibbs phase rule. This problem explores some of the complications of counting components. |
|
7-5 |
A third problem based on the Gibbs phase rule. Part (e) is tricky. |
|
7-10 |
Another T/F problem. This one concerns phase equilibria. |
|
7-11 |
A problem based on the common substance water. A number of sets of temperatures and pressures are given. Which phase of water is stable (i.e., has the lowest chemical potential = molar free energy) in each case? |
|
7-37 |
At what temperature are two solid forms of tin at equilibrium? The difference in entropy betwee the two forms is more important that the difference in density. |
|
7-55 |
Another of Levine's very useful thought problems. |
