Chem 160: Physical Chemistry for Bio-Sci Students

Syllabus


General Information

Office Hours and Outside Help
My office is Cook 119. I will be there specifically for Chem 160 office hours, times of which will be announced after I have collected everyone’s schedule. At any rate, I will be exceedingly available at other times by appointment. I encourage you very strongly to use these times to clear up difficulties in understanding the material as soon as possible. Obviously, the next lecture will be that much easier to follow. Review sessions may be scheduled if student demand warrants it (collecting schedules will be helpful here, as well). Also, in addition to just stopping by my office to see if I have a minute right then and there, you can get in touch with me via the means listed on my Contact Page
Prerequisites
Chemistry 160 is a one-semester survey course in physical chemistry. The official prerequisites listed in the UVM catalogue are: one year of introductory chemistry (Chem 31, 32) and one semester of introductory physics (Phys 21, 42). Also, it is expected that students have had an introduction to calculus, because any solid treatment of physical chemistry requires it (and our text book expects such).
Fulfilling the Minor
This course is one of the choices that one can use to satisfy a minor in Chemistry in conjunction with a year of Organic Chemistry. However, if you found physics (and math) to be somewhat difficult, it may be advisable to enroll in one of the other options. For example, this semester you could take Chem 131 (Inorganic Chemistry - no math/physics prerequisites). Also satisfying the minor requirement is Chem 221 (Instrumental Analysis - although you will not have the official prerequisite of physical chemistry satisfied, the catalogue lists that instructor’s permission may be granted). Also, if your timetable allows it, you might take Chem 121 (Quantitative Analysis - no math/physics prerequisites) next Fall.

Course Structure

Textbook

We will be using “The Elements of Physical Chemistry with Applications in Biology” by P.W. Atkins [third edition, published by W.H. Freeman]. A quick look through our text will make clear that we will be hard pressed to cover all of the topics in the entire book. However, we will cover the bulk of the text, and select material so that the end result will be a topically cohesive survey of physical chemistry concepts and applications.

As a general outline, we will follow the order in which the year-long course in physical chemistry is taught. We will start with the subject of quantum mechanics and its applications to chemical systems, chapters 12-14. Next comes selected topics out of the subject of spectroscopy, chapters 17-19. Kinetics forms the next subject, covered in chapters 10-11. In the second half of the course we will cover the subjects of thermodynamics and equilibrium, chapters 1-9. We will have our work cut out for us!

The rule of thumb to use in this course is that if a concept is not discussed in lecture, you don’t need to know the corresponding passage of a chapter; however, you are responsible for everything in the notes. Also, be aware that material may be presented by me differently from the way the author has done a given topic.

Responsibilities

From the above, it should be very clear that missing a lecture can be extremely detrimental to your continued understanding of the material. Thus, I expect perfect attendance. If you have a valid, serious reason to be absent, you must call me beforehand. It will be up to you to get all the information presented at the missed class.

Secondly, I expect you to come prepared for each lecture by having read ahead in the textbook. The lectures won’t seem so mysterious if you know what is coming. If I find that the class, in general, is not keeping up with the outside reading, I may “pop” a quiz on you (which will count in the points total).

Finally, I expect you to participate in class by being alert and ready to answer questions. I find it personally insulting to see the occasional student spacing out, looking off into space, or exhibiting a case of “sleepy eyes”. This expectation falls in the rubric of common courtesy or mutual respect. Please make a determined effort to absorb all the information from each lecture.

Homework
I will assign homework sets topically, i.e., per chapter. They will not be graded, but answers will be made available and we can go over them during discussion/review sessions that may be scheduled, or perhaps during lecture. It goes without saying, however, that actually doing the problems on your own firms up the knowledge that is in your head.
Quizzes
I have found that students will keep up their progress in learning the material better if they are rewarded on a regular basis for doing so. Every Friday that is not an exam date I will send out a quiz that you must complete that weekend - it is due in my mailbox by noon on Monday. It will cover the material presented in the previous two lectures and be worth 10 points each. There are 10 such Fridays (January 21, 28, February 4, 18, 25, March 18, April 1, 8, 22, 29) and thus the quizzes in total will contribute 100 points, which is the equivalent worth of one exam.
Semester Exams

The semester exams will not be given during lecture time. For a Tuesday/Thursday sequence, there are only 28 class meetings, and eliminating >10% of the lectures does not give you your money’s worth. They will instead be given on Fridays, time to be determined. I will accommodate your schedule, and collect everyone’s schedule for that reason. This is an advantage for students because I will be able to let you have as much time as you need to complete the exam.

As was mentioned earlier, there is a tremendous volume of subject matter covered in this course. In order to limit the sheer amount that you can be tested on, we will divide the semester’s lectures up into four portions, and give an exam on each of the four portions. Thus the exams will fall on the following days:

Exam #DateMaterial Covered
Exam 1Friday, February 10lectures #1 - #7
Exam 2Friday, March 10lectures #8 - #14
Exam 3Friday, April 14lectures #15 - #22
Exam 4Friday, May 12(or earlier)lectures #23 - #28
Comprehensive FinalFriday, May 12All Lectures

Two related issues to keep in mind are that I will not discuss exam material on the day of the exam, and that my standing policy is that no make-up exams will be given. Please make your travel plans now with the exam schedule in mind. If you have an unavoidable conflict, you must talk to me immediately.

Final Exam
Your Final Exam is scheduled for Friday, May 12, at 8:00 a.m., and it will have two components. Part one covers the portion of the course not covered by regular exams; it will be graded separately and be worth the same as the other three exams (100 points). Part two is a comprehensive component that will be multiple choice. This portion of the Final Exam will be worth the equivalent of two regular exams (200 points). There is a possibility of administering the fourth exam (material from the last six lectures) a number of days earlier. The advantage of this is that (i) you would be clear on your level of knowledge of that quarter’s material and can make adjustments, and (ii) you could dedicate study time on a comprehensive review for the final instead of studying for two different types of exams. We will have a class discussion on your preferences.
Course Grading

As set out above, you will be working toward accumulating points from among the 10 quizzes (100 points), 4 exams (400 points) and a comprehensive final (200 points). Simple math tells you that each exam is thus worth approximately 14%.

Clearly, an actual letter grade cannot be assigned to any one exam. Furthermore, course grade assignment is not done on an immovable, absolute scale. Instead, your performance will be judged with respect to the class average, at the end of the semester. Although I can not at this time predict the difficulty of the exams and the overall strength of the class, I can say that the average score for my physical chemistry courses has always been around 65-70%. In a large statistical sample, for this course a performance of 65-70 earns a B-, with 5-point intervals for grade changes. In smaller classes the average can vary; also, depending on the overall performance of the class, the average grade may be set higher or lower.

The above grading scheme is based on the assumption that attendance is perfect, that students come prepared, and that class participation is active. If a student is on the borderline between two grades, I will use these criteria to evaluate whether a move up or down is warranted.

Class Notes
My own experience tells me that it is hard to follow the thread of a discussion if you are furiously copying from the blackboard. Instead, I will hand out and/or post on my website copies of my notes before each lecture, which you can then annotate. If, however, you are the type of student who learns better by taking your own notes, you should of course do so, and then use my notes as a backup.
