CH302 Random Musings April 12, 2007 1. We are rolling downhill to the finish line. In these musings are the question types for Quiz 5, Exam 3 and the Final Exam. Be thinking about the strategy you will be using to earn the grade you want in this course. Some of you will need to think about how to achieve something close to perfection on exam 3 so you can be exempt. Others will need to be concentrating on preparation for the final since they know it will be the way they earn the grade they want. E-mail me if you have questions about the strategy you will use. 2. A reminder that except for about 30 of you who are busting the curve on my exams, the rest should absolutely be getting your extra credits in. Details are in last week’s musings but basically you need to go to a scholarly talk and tell me about it, and go to a poster session and tell me about it. 3. One of my children is playing his junior year college piano recital, which is kind of a big deal, and being like me he waited till the last minute to reserve a performance hall and now if I am going to see it I have to be in Houston at 5:30 on Thursday the 19th, which means I have to miss class. So this is the reason I moved the Quiz 5 date. The day of the quiz I am going to ask Vanessa to give the introductory talk on organic nomenclature since she is an organic chemist and I most definitely am not. I haven’t asked her yet, though, so I will now. 4. If you can’t take the quiz on the 19th, I will give it to you on the 17th. E-mail to let me know and I will make arrangements with you but basically I will give it in my office from 1:30 to 2 pm before class and from 3:30 to 4 pm after class. E-mail to let me know that you will be taking it then and then show up in my office, WCH 2.222. 5. The question types for quiz 5, to be given April 19th, are shown below. They cover the more complicated material from electrochemistry and all of kinetics. • relating E, ΔG and K • stoichiometry calculation from current • calculating cell potentials (Nernst) • assigning rate expressions • method of initial rates • integrated rate law calculation • Arrhenius calculation • reaction mechanisms 6. Worksheet and lecture note uploads—Neal and I have been busy boys: • Neal has updated worksheet 11 to make a few more corrections (as of 4/11) and apologizes profusely for all transgressions. • I have posted a handout on how to determine the order of a reaction • I have posted a worksheet on how to perform real kinetics calculations from raw concentration time data. It is a nice worksheet but requires you really know your stuff. • This weekend Neal will post worksheet 12 which will sample kinetics problem types to be found on the quiz. • I have posted the lecture notes from class on how to perform integrated and differential rate law calculations (Tuesday’s lecture) • With any luck I will post the final kinetics notes on theory and mechanisms this weekend. (Boy this class is a lot of work). 7. Question types for Exam 3 are found below: Question Types from Electrochemistry 1 relating E, ΔG and K2 stoichiometry calculation from charge or current 3 calculating cell potentials 4 famous batteries Question Types for Kinetics 5. assigning rate expressions 6. relating reaction order to rate 7. units of rate constants 8. method of initial rates 9. integrated rate law calculation 10. integrated rate law calculation 11. extracting information from straight line plots 12. kinetic theory—collision 13 kinetic theory—transition state 14. combined Arrhenius calculation 15. reaction mechanisms 16. Ea and potential energy surfaces 17. famous catalysts Survey of Chapters 14-16 and 18, 19 18. properties and reactivity of alkali metals 19. properties and reactivity of alkali earths 20. properties and reactivity of the B family 21. properties and reactivity of the N family 22. properties and reactivity of the C family 23. properties and reactivity of the O family 24. properties and reactivity of the halogen family 25. d-block physical property trends 26. d-block chemical property trends 27. hydrocarbon nomenclature 28. hydrocarbon reactivity 29. organic functional group nomenclature 30. organic functional group nomenclature 8. I am posting the 60 questions for the final exam today. The source is pretty simple. I took the 3 thirty question tests from the semester and pulled out about 20 questions from each. This is very much a traditional cumulative final covering pretty much everything I have taught. And in keeping with my philosophy that I don’t care when you learn it, as long as you learn it, being able to prove to me on May 15th that you know the material well enough for an A is good enough for me. 9. For those of you taking the final for everything, I will tell you once again, if you want to have a chance at an A, you have to get organized. And being organized means making sure your brain knows what is on the final before you start filling it with stuff that otherwise has no place to go. So memorize the question types, all 60. Do it by sections and it doesn’t hurt as much. If you don’t want to do this, don’t bother coming to me for help and forget about getting a good grade on the final.. 10. Public Service Announcements: A way to earn extra credit: Stem Cell War / Friday 4/13/2007 MEZ 1.306 / Science session 11am, Ethics 2pm, Policy 3pm http://cns.utexas.edu/ds/stem_cell/ The 2007 Stem Cell Symposium will feature lively debates of all perspectives from leaders in the stem cell debate. Each of the three sessions -science, ethics, and policy- will address the controversial questions of "What cures can stem cells promise?", "Do embryos have rights?", and "Should tax money fund embryonic stem cell research?". The format is moderated debate and open-floor Q&A so UT students –future leaders and voters– can get their questions answered and make educated decisions on this momentous issue, no matter their stance. Featured speakers include adult and embryonic stem cell researchers, member of President's Council on Bioethics, Executive Director of Texas Alliance for Life, and the activist who seeks to amend Florida's constitution to support embryonic stem cell research. 11. Poetry Corner. I wasn’t going to do any more depressing poetry this year, but then one of your class mates asked me to include part of Eliot’s The Waste Land, which got me to
