I think that having the weekend to review some of the Transition State Theory and the mechanism stuff, everyone should have an opportunity to demonstrate what they understand. Check out our textbook on pages 689 - 692 (Q5) and pages 692 - 697 (Q8). Problems 16.62, 16.63, 16.64, sample problem 16.8, 16.115. I'll see if I can not come up with a couple problems for everyone to try on Monday. We'll count this assignment as a PS also.

ATTENTION!!! For Friday, October 19, 2001 I want you to complete Question 5a - 5e and Q8 on Exam II and to turn in the answers at the beginning of class. The exam is available in a pdf file, down load it and answer Q5 and Q8 for Friday. I will probably count these two problems as a Problem set.

Here is an InClass exercise to practice on.

The PLE for Friday's class is available. At the end of the PLE are questions from Silberberg and PS7 that I think you should be able to do. Try them. If you have questions send an e-mail, use the forum, or ask them inclass.

For class on Friday (besides Q5 and Q8 on the exam which you must turn in!) you should be able to do PS7.1 and PS7.2 before class. If you are a real animal you may be able to PS7.3. You do not have to turn in the PS7 problems, but you should try to do them. If you have problems with PS7.2 say something in class when I ask, "Any questions, comments, or concerns?' I will begin class on Friday with PS7.3. It is always a great idea to have your PS in front of you in class, because I'm covering everyone of those questions during lecture.

Grades are up. The TAs are giving me new homework and lab grades and I'll be posting those in the next few days. I predict the class average will move back up several percent when those grades are added. Remember, if you have any concerns, drop by and we can talk. I will be in OKC tomorrow morning and into the early afternoon.

Right now the class average is 61%. This is down a few % from where we were just before this exam. Even though the exam average was low, the class average has fallen only a little bit.

General comments about Exam II;

• the average on this exam is not going to be pretty!...all sections are reporting and the average is 51.
• the good news is the high on the exam so far is a 97! we have a repeat offender!
• I graded Q5 d and e (the question asking for a description of the experiment needed to determine the order of the reaction between X and Y) and most everyone did a wonderful job describing how to determine the order by plotting ln[X] vs time and [X]^-1 vs time. However the reaction was not a simple reaction. I was looking for a discussion in terms of the method of initial rates. It looked like everyone had focused really hard on how to answer the plotting question so I congratulate you on that, unfortunately it was not what was needed on the problem. Part e of the question did not go well either. The performance on the mechanism problem, Q8, was kind of dismal. (Does anyone remember the assignment I gave you at the end of class on Wednesday, October 10, 2001?).

PS7 was distributed in class on Monday, October 15, 2001. It is available at the PS link.

New grades are now available (as of 10/3/01). Note that I now have grades for each part of the course: homework, lab and exam. With that information I can predict your final course %. That % is located in the lower left corner of the page. That is what I PREDICT. Check the General Information link on our web site to see what grade is equivalent to the %. If you have any questions e-mail me, or drop by. I'm out of town on Thursday (most), but I'll be around on Friday. Any errors in your grades see your TA.

The new grade access form is working. To get your grades you click on our grade link. Your name is the first initial of your first name and your last name as a lowercase string. For example, John Gelder is jgelder. Your password is the SID# that you gave me when you completed the SID form on our web site. If you have any problems send me an e-mail. It is working now but exam grades are not up yet.
