Kinetic theory of gases at equilibrium. 2. Instructor Information Dr. Mortaga Abou-Krisha My office is on the third floor SR59. My is m_abou_krisha@yahoo.com 3. Office Seek help when you need it! The best time to catch me at my office is during my office hours, or by appointment. In the following the office hours Monday 12:30 14:20 Tuesday 10:00 11:50 During office hours I will be pleased to speak with students without an appointment. If you would like to see me at another time, please arrange for an appointment before or after class or by . Since office hours give students the opportunity to ask in-depth questions and to explore points of confusion or interest that cannot be fully addressed in class so please come to the office hours. 4. References: Required Textbook & Internal Website I shall use Physical Chemistry. 8th Edition New York, NY: W.H. Freeman and Company, 2001 ( ISBN: ) by Atkins, P., and J. de Paula. Students are required to purchase the textbook/materials (it is an obligation). The book contains the lecture notes as well as activities for the students to take part in; the book serves as a workbook. Other essential referencesare: a) K. J. Laidler, J. H. Meiser, B. C.

5 Your course grade will be based on Final Exam, Midterms, Homework, Quizzes, Participation, Attendance and Project. Midterm 1: 20 % A + : 95% % A: 90% - 94% Midterm 2: 20 % B + : 85% - 89% B: 80% - 84% Intermediate exams:10 % C + : 75% - 79% C: 70% - 74% Quizzes, Homework, Attendance, Participation: 10% D + : 65% - 69% D: 60% - 64% Final Exam: 40 % 7. Student Attendance/Absence Only three situations will be considered as possible excused absences: Occurrence of a birth or death in the immediate family will be excused. ( Immediate family is defined by the University as spouse, grandparents, parents, brother, or sister). Severe illness in which a student is under the care of a doctor and physically unable to attend class will be excused. Students are not excused for a doctor's appointment. Do not make appointments that conflict with rehearsals. Notes from the University Health Center will be accepted. 8. Appropriate Classroom Behavior Please be on time for class. It is distracting to me as to your other classmates to have people come in late. Please switch off pagers and cell phones before entering the classroom. Abstain from bringing friends or small children to the classroom. Be courteous and considerate to your other classmates and to me. Do not ask for extra credit, as none will be given. Homework may be assigned, but not collected. Do the assigned homework. NOTE: This syllabus is tentative and should not be considered definitive. The instructor reserves the right to modify it (including the dates of the tests) to meet the needs of the class. It is the student responsibility to attend class regularly and to make note of any change. Page 5 of 5 CHM 241
