LYCOMING COLLEGE PHYSICAL CHEMISTRY II 331W SPRING 2009 Dr. Mahler p. 1 Instructor: Dr. Charles H. Mahler, Phone 321-4351 or 322-8840 (h), [email protected] Office Hours: Heim 202, MWF 11:10 AM-noon, MW 1:30-2:30 PM, by appointment, or drop by. If you have questions or comments about anything in the course, please come see me. I am ready and willing to meet with you and discuss your concerns, answer questions, explain concepts, solve problems, etc. I would rather help you to understand something before a lab or test or other assignment, than to find out you don't understand it while grading your work. CLASS: MWF from 9:00 to 9:50 AM in Heim 215. LAB: T from 7:45 to 11:35 AM in Heim 204. Prerequisites: Chem 330 (and its prerequisites) Materials for Course: Physical Chemistry, 8th Ed. Peter Atkins and Julio de Paula; ACS Style Guide, 3rd Ed. Calculator with logarithmic and exponential functions (no passing or sharing allowed in exams); Bound Laboratory Notebook with quadrille pages (for lab use only); Safety Glasses or Goggles; The 2008-2009 Laboratory Manual for 330-331W. Evaluation and Grading: Grades will be based on the following weighting scheme: 3 Exams (45%), a Final Exam (20%), Lab, including Writing Project (25%), and Homework and Quizzes (10%). Because this course is Writing Intensive, special emphasis will be placed on learning through writing in all assignments, but especially the Writing Project (see below, manual). 3 extra credit points (to a limit of 20, on a 1000 point scale) will be given for each Chemistry Colloquium attended. Alternative extra credit will be available for those whose schedules conflict with colloquium (but you must see me to arrange this by Friday, March 27, 2009). The final exam will be a comprehensive, multiple-choice test, prepared by the American Chemical Society, covering both semesters (330 and 331W). ALL EXAMINATIONS ARE COMPREHENSIVE, ESPECIALLY THE FINAL. The following scale will be applied to determine the final letter grade: A > 90% > B > 80% > C > 70% > D > 60% > F . Plus and minus grades are included in these ranges and will be determined at the end of the semester. Adjustments to this scale are possible, but unlikely. Exams: Hour Exam 1 Tuesday, February 10, 2009 (in lab) Hour Exam 2 Tuesday, March 17, 2009 (in lab) Hour Exam 3 Tuesday, April 14, 2009 (in lab) Final Exam 1:00 to 4:00 PM, Monday April 27, 2009 (in lab) Content: Physical Chemistry provides the theoretical basis for explaining and interpreting chemical systems by focusing on their structure and the energy and time involved as they change. In this course we will study and attempt to understand many of the basic principles and phenomena of chemical systems including Molecular Motion & Kinetics, Quantum Theory, and, time allowing, some aspects of Spectroscopy and Statistical Thermodynamics.LYCOMING COLLEGE PHYSICAL CHEMISTRY I 330 SPRING 2009 Dr. Mahler p. 2 Lecture Attendance and Absences: Lecture attendance with calculator and textbook is required. All unexcused lecture absences after three will be penalized 2 percent (of total possible points) per day. Only absences notified ahead of time may be excused. Notification is expected as soon as possible for planned (athletic events, class trips) or emergency (illness) absences; call or e-mail me or the Department Secretary (321-4180). The cause of absences must be verified by the Dean or substantiated (note from coach or parent, doctor's excuse, etc.). Exam and Lab Absences: No make-up exams will be given. The (cumulative) final exam grade (as a %) will be substituted for one excused absence exam grade (as a %). Barring exceptional circumstances, all subsequent missed exams will receive a grade of zero. Because students often work in groups in lab, absences hurt everyone and should be avoided. Make up labs will vary (and may not be possible), depending on the circumstances of that week's experiment. In some cases, students may be allowed to work outside scheduled lab hours by first obtaining permission from a chemistry professor (who must be in the building while they work and be notified when they leave), and then having a "buddy" present. Quizzes: There will be seven quizzes this semester: Jan. 19, Jan. 26, Feb. 2, Feb. 23, Mar. 9, Mar. 30, and Apr. 6. Quizzes will be given Mondays at the end of the period, with the lowest quiz grade dropped. Homework: Each chapter has a set of recommended problems which students are strongly encouraged to work. In addition, some days there will be graded homework problems assigned. These are due at the start of the next lecture (or as soon as you enter lecture, if late), and we will go over the solution in that lecture. Many students find it useful to keep a copy of the problem to review. No late homework will be accepted and the lowest homework grade will be dropped. If you must be absent, have someone else take notes and hand in any assignments for you. Almost all of the ‘discussion questions’ are useful (i.e. the first several exercises for each chapter). Note that answers for the (a) exercises and some problems are given in the back of the textbook. Chapter 21 Exercises 21.1 (mean speed), 2 (mean speed, mean free path, collision frequency), 4 (mean free path), 5 (collision frequency), 6 (mean free path), 10, 11 (effusion), 15 (viscosity), 20 (thermal conductivity), 25 (limiting molar conductivity). Chapter 22 Exercises 2, 4, 5, 6, 7, 8, 9, 10, 11 (rates, rate laws, rate constants and half lives) 14 (Arrhenius). Problems 13, 20 (Mechanisms) Chapter 23 Exercises 1a and b, 2, 3, 4, 5 (all solving mechanisms), 6 (Michaelis Menten). Chapter 8: Exercises 3 (uncertainty principle), 4 (photon tricks), 8 (Black Body Radiation), 10 (de Broglie relation), 13 (Ionization, like photoelectric effect) Chapter 9: Exercises 1, 4, 5, 6 (particle in a box) 8, 9 10 (harmonic oscillator) Other chapters to be announced. Review Sessions, Keys, and Scores: A review session will be held before each exam in Heim 204 (the lab) from 8:30 to 10 PM the Sunday prior. Final exam review time is TBA. There is a class Moodle page. The syllabus will be there and at: http://www.lycoming.edu/chem/spring2009/331syl.htm. Homework and exam keysLYCOMING COLLEGE PHYSICAL CHEMISTRY I 330 SPRING 2009 Dr. Mahler p. 3 will be reviewed in class and/or posted on Moodle. Scores will be posted using a secret, four-character code, unless you write me not to by 1/16/2009.
