  1. Lecture 1 1/19/05 CHE132: General Chemistry II Dr. Jimmy Hauri

  2. Office:253 Testa Science Building • Email:jhauri@assumption.edu • Office phone:x 7359 • Office hours:MWThF 9:30-12

  3. Chemistry and Chemical Reactivity (5th ed.) by Kotz and Trechel Grading: Weekly Quizzes (8 x 10 points/each) 80 Midterms (3 x 135 points/each) 405 Final (cumulative) 150 Laboratory 250 Paper 90 Class Participation 25 Total 1000

Quizzes: • A short quiz will be given every Friday. • No make-ups, but the lowest scores will be dropped, so that only 10 quizzes count toward final grade. • Class participation:Easy to get full credit, just attend class and be involved with class discussion • Calculator policy: Students may only use non-programmable calculators during exams.

  5. Academic Dishonesty:Don’t cheat!!See A. C. Student Academic Handbook for consequences. • Paper:5-page paper on a chemistry topic. • Extra credit: 2 – 5 points per seminar. Turn in a ~1-page summary within a week of an approved seminar for credit. Quality of summary determines points.

  6. Exam schedule • Exam 1 – Wednesday, February 16, 2005 • Exam 2 – Wednesday, March 23, 2005 • Exam 3 – Monday, April 18, 2005

  8. A + B ↔ AB • Rate based on: • Constant • Concentration

  9. At Equilibrium: • Rates (forward and reverse) are equal • Concentrations stop changing • Reactions are still going • ‘dynamic equilibrium’ • Equilibrium not the same thing as kinetics

  10. Rates are equal

  11. Law of Mass Action
