1 Lecture Instructor Information Lecturer: Dr. Cherice M. Evans Office: Remsen 211 or 211B Office hours: M,W; 10:00 11:30 am in Remsen 211 2 Course Information Lecture times: Requirements: M,W; 8:00 9:50 am. Room 105 for CHEM 211 (BA) and CHEM 770 (MA) A scientific non-graphing calculator Graphing calculators will NOT be allowed on any in-class quiz or examination. If you do not have a non-graphing calculator for such assessments, you will be required to work the examination without a calculator. Textbook: Andrew Cooksy, Thermodynamics, Statistical Mechanics and Kinetics (Pearson, New York, 2014). Online homework will not be used with this textbook, so do not hesitate to purchase a used version of the book. At last check, the cost of a used version was around $24.00 at Amazon. You may use a different book (such as McQuarrie or Atkins). However, you are responsible for determining the material that we are covering. Prerequisites: A grade of C or better in MATH 152 or 143 or 158. However, students with a C in one of these calculus courses or who have transferred calculus or who have not taken calculus within the last three years will find CHEM 211/770 challenging. A grade of C or better in CHEM 1144 and 1141. Course Description: Attendance: The fundamental principles of modern chemical thermodynamics and kinetics are presented. It is important to note that there is a direct correlation between on-time class attendance and performance in the class. All announcements about changes in in-class quizzes or take-home exams will be made at the start of class. It is the student s responsibility to obtain copies of any such announcements from his/her friends at the end of class. 1
Queens College policy states that by registering in a course you are assuming the obligation to fulfill the requirement set the course by the instructor. Although absence in and of itself shall not affect your grade, you are responsibility for such activities as participation in class discussions, laboratory sessions, field trips, preparation of papers and reports, and the taking of quizzes and examinations; any or all of which may constitute a component in the final grade of the course. Although attendance may not be required for a final grade in a course, it may be required to retain eligibility for financial aid. Computational Resources: Course Objectives The high speed computer in Remsen 211B will be available Monday Thursday from 10 am 6 pm for use on computational homework. Students must sign up for time and are not allowed to stop other student s computational work. NIST software, computational software and data analysis software will be provided through Blackboard for student use. The course has the following objectives as required by a certified ACS physical chemistry course: Thermodynamics and equilibria including: Standard functions (enthalpy, entropy, Gibbs energy) and applications Microscopic point of view especially for entropy Chemical potential applied to chemical and phase equilibria Non-ideal systems Standard states Activities and the Debye-Hückel limiting law Gibbs phase rule and phase equilibria Single and multi-component phase diagrams Thermodynamics of electrochemical cells, elastomers and coil-type molecules Statistical thermodynamics including: Maxwell-Boltzmann distributions Standard thermodynamic functions expressed in partition functions Partition function expressions for atoms, rigid rotors, harmonic oscillators Einstein and Debye crystals Chemical kinetics including: Differential and integral expressions with emphasis on single-step and multi-step phenomena of various orders Relaxation processes Derivation of rate laws from chemical mechanisms Steady state approximation and relaxation processes Collision theory, absolute rate theory and transition state theory Applications to chain reactions, polymerization, surface chemistry and photochemistry 2
Pedagogic Approach: Mastery (i.e., learning), not memorization! You cannot master chemistry by just reading the book (or, more commonly, just looking at a compendium of worked problems). You will only master topics in chemistry by practicing daily. The material in thermodynamics and kinetics is mathematically challenging, which makes it difficult to distinguish understanding of the physics with problems in the mathematics. Thus, you will master this material by attempting problems, failing to solve them, and trying again. Mistakes are not the end of the world, as long as you learn from them. The end of the world occurs when you give up trying the problem. 3 Grading Policies Most students give up on a problem when they become frustrated because they cannot see a way to work the problem. However, frustration is a good thing! Frustration indicates that you are close to mastery. Thus, when you feel this, take a deep breath (or several) and refocus on the problem. When you are problem solving (and most of your time should be spent on this), TURN OFF YOUR CELL PHONE AND ELECTRONIC GADGETS. Electronic gadgets allow you to disengage from that feeling of frustration and interfere with the learning/mastery process! Do not feel bad or panic if you are spending 10 or more hours/week studying for physical chemistry. This is normal.

On each quiz, two of these problems will be selected as bonus. This bonus must be submitted by 12:00 pm on the day of the quiz. Notes: In either the BA or MA grade determination, students who have a course grade of C but who earned a grade > 64% on the final ACS standardized examination will receive a grade of C. 4 Background Knowledge Freshman chemistry: The instructor will assume that all students remember the basic information covered in freshman chemistry. This information includes balancing chemical reactions, basic inorganic nomenclature, stoichiometry and percent yield. Students should also review the simplistic overview of quantum mechanics, thermodynamics and kinetics presented in CHEM 1144 as well as Lewis structures. The instructor will not take the time to cover this material, but will build upon your existing knowledge. Thus, if you do not feel comfortable with your understanding of this material, you may want to practice using the problems posted in Blackboard. 4
Calculus: All students enrolling in this course should have completed two (or three) semesters of a standard single-variable calculus course that covered differentiation, integration and sums and should have earned a grade of C (not C ) or better in all semesters of this requirement. However, physical chemistry is a mathematically intensive course. With this being stated, CHEM 211/770 is the least mathematically intensive course of the two semester physical chemistry sequence. The primary skill that you need from your calculus is the ability to differentiate and you should be able to differentiate ANYTHING! However, the instructor understands that it may have been a while since calculus was completed and/or that students may not feel particularly comfortable with their mathematical skill set. If this is the case, you will want to practice using the problems posted in Blackboard. 5 Types of Assignments In-class Quizzes Take-home Homework: Take-home Problems: ACS Final Examination Each quiz will be designed as a 60 minute quiz, although students may arrive and start the quiz at 7:00 am if they chose. The quizzes will be open notes and will be similar to the practice homework problems posted in Blackboard. There will be two take-home homework assignments: one on refrigerators and engines and one on computational chemistry. These will be posted in Blackboard at least three weeks before the due date and will take significant amount of time to complete. The MA students will be required to work a set of take-home problems. These problems will be posted and will be graduate level problems. Thus, plan for each problem to take 1 10 hours (depending on ability and background). The final examination will be a standardized ACS examination. Students may borrow the study book from the instructor, but may not remove the book from Remsen or xerox the book using the department copy machine. 5
