Chapter 1: Probability, Distributions, and Equilibrium
Chapter 1 quiz
|
| a. |
You should know how probability, number of ways, and number of ways total are
related. [our first equation]
|
| b. |
You should be able to apply that understanding to simple card/dice-type problems.
[calculation]
|
| c. |
You should be able to determine the most probable distribution of molecules in an
isotope exchange reaction involving some number of moles of various molecules
initially. [calculation]
|
| d. |
You should be prepared to discuss le Chatelier's principle in terms of probability quite
apart from any calculation. [rationale]
|
| e. |
You should be prepared to discuss why we are allowed to focus on the most probable
distribution. [rationale]
|
Chapter 2: The Distribution of Energy
Chapter 2 quiz
|
| a. |
You should be able to calculate W for any distribution of just a few quanta of energy in
a few particles. [equation]
|
| b. |
You should be able to demonstrate that you know what a "microstate" is. [description]
|
| c. |
You should be able to predict the most probable distribution of energy in a system
containing mole-quantities of particles and mole-quantities of energy quanta, provided
the energy level separations are identified. [equation]
|
| d. |
You should be able to discuss the role of temperature, and what effect it has on the
most probable distribution of energy in a system. [discuss]
|
| e. |
You should be able to discuss the effect of energy level separation on the most
probable distribution of energy in a system. [discuss]
|
| f. |
You should be prepared to discuss why we only need to consider the most probable
distribution of energy in molecular systems. [rationale]

Chapter 3: Energy Levels in Real Chemical Systems
Chapter 3 quiz
For this chapter, all the energy equations will be provided for you--no need to put them in
your calculator. I think you will find that the calculations are just one part of
the whole here. The exam will not just be a rehash of the homework. Take a look at those homework problems and
ask yourself, "What was the lesson here?" Look at the answers. Compare numbers.
Do not assume that the lesson was simply how to use your calculator and get the "right" numerical answer. You
need to go beyond that. What do the numerical results tell you in relation to chemistry? Be prepared to use
your calculator, but not anywhere near the amount you have used it on recent homework
assignments.
|
| a. |
You should be able to describe what each of the following terms means: electronic
excitation, vibration, rotation, translation. [description]
|
| b. |
You should be able to calculate reduced mass. [equation]
|
| c. |
You should be able to identify which energy equation goes with which type of
excitation. [equations]
|
| d. |
You should know what the various variables "R" "d" "a0" "m" etc. refer to in the
energy equations. [description]
|
| e. |
You should know in general why one type of energy level system is more or less
closely spaced than another. [description]
|
| f. |
You should be able to compare two substances and predict which has the more closely
spaced energy levels in one or more of the types of excitation. [description]
|
| g. |
You should be able to understand and use energy diagrams that show one or more
electronic state and its associated vibrational and rotational levels. [discussion]
|
| h. |
You should be able to discuss at least two of the applications presented in the "putting
it all together" section and later sections in this chapter. [discussion]
