A Very Brief Random Musings—April 28, 2011 1. You all did extremely well on the last quiz, with an average of over 80% and nearly 200 students getting perfect scores. It looks like things are setting up well for exam 3, though the electrochem and kinetics questions on the exam will be a bit more of a challenge. 2. There is an exam 3 next week with the usual details to follow on Tuesday. One big issue to keep in mind: Technically the make-up exam 3 shouldn't occur during dead days after the last day of class. I try to argue it with the Registrar but they are never pleased. So here I the compromise: Examination should not occur during dead days after the last day of class and can occur only under the most extreme of circumstances. So I can offer the make-up on Sunday night, May 8, only to students with a valid conflict. So you are expected to take it Thursday night May 5 unless you provide evidence, not just that a class is scheduled, but that it is actually meeting that night. 3. The following are true as we get ready for the exam 3: I will have a practice exam ready on Friday evening or early Saturday morning The TAs will have a practice exam ready on Sunday. The exam is calculator free. My help sessions are in the classrooms I will have a review session on Monday evening at 9 pm in this room. Travis will have a review session on Tuesday evening. Specific details will follow. 4. Question types for Exam 3 are repeated below: Question Types for Electrochemistry 1. balancing a chemical reaction in acid or base 2. assigning cell convention in an electrochemical cell 3. understanding the table of standard half cell reduction potentials 4. Nernst equation calculation 5. ranking oxidizing and reducing agents 6. electrolysis 7. stoichiometry calculation using the Faraday 8. current calculation 9. calculation involving relationship between E, K and ! G 10. famous battery 11. rust in the real world Question Types for Kinetics 12. calculating reaction rates 13. method of initial rates 14. integrated rate law calculation 15. integrated rate law calculation (half life) 16. extracting information from straight line plots 17. kinetic theory—collision 18 kinetic theory—transition state 19. combined Arrhenius calculation 20. reaction mechanisms 21. reaction mechanisms 22. E a and energy profiles 23. famous catalysts Descriptive Chemistry 24. properties and reactivity of alkali metals 25. properties and reactivity of alkali earths 26. properties and reactivity of the B family 27. properties and reactivity of the N family 28. properties and reactivity of the C family 29 properties and reactivity of the O family
