1 Chemistry 313 Course Syllabus / Fall 2006 Instructor: Dr. Caleb A. Arrington Course Number and Title: Chem 313 Physical Chemistry I (Thermodynamics) Meeting Place: RMSC-308 Meeting Time: M,W,&F 10:30 11:50 Instructor Office Hours: M 2:00 pm 3:00 pm Th 10:00 am 11:00 am F 9:00 am 10:00 am Instructor Caleb.Arrington@Wofford.edu Instructor Campus Phone: (864) Course Webpage: Course Description: Chemistry 313 is an introduction to chemical thermodynamics focusing on the mathematical description of state and path functions as they apply to the changes of energy and equilibrium in molecular systems. Goals of Course: To explore the physical relationships in the field of thermodynamics focusing on calculus based mathematic as it relates to energy transformations, and systems in equilibrium. The specific learning objectives of the course are given below. Course Evaluation: Graded course work is covered with three assignment types: Homework, and In-Class Exams. The contribution to the final course grade made by each assignment type is given below. Homework: 20 points 200 points Exams: 100 points 300 points Final Exam: (ACS Thermo Exam) 200 points 200 points Total 700 points Homework: Most class meeting will have a corresponding set of questions to be complete as homework. These questions will help you put into practice the concepts that we discussed during the classroom time. Homework assignments will be due weekly (Fridays) during the semester.

2 Exams: In-class exams will occur after the following material has been covered: Chapters 1 4 Wednesday, Oct. 4 Chapters 5 6 Friday, Nov 10 Chapter 7 9 Wednesday, Dec 6 Final exam (ACS Thermodynamics Exam) Tuesday, Dec. 12 (2:00 pm) Technology Skills: Students are expected to be proficient in spreadsheet software, and symbolic mathematics programs such as Mathcad. Instructional Format: This investigation of chemical thermodynamics will be centered on the engaged learning text of Moog et al. Each class meeting will focus on discussing topics and working problems in thermodynamics. By these discussions we will replace the traditional lecture format with a dialogue in thermodynamics. Absence Policy: Success in the course will rely heavily upon class attendance. Your comprehension of the lectures will be greatly enhanced if you read the text prior to attending the corresponding class discussion. Two consecutive class absences will result in a note being sent to the Dean of the College expressing my concern for your success in this course. In the event of a University activity or a significant illness, arrangements for taking an exam at an alternate time may be made by scheduling with me prior to the exam. Missed exams without prior arrangements may not be retaken. Calculators are not to be used as information storage devices. Using calculators as such is considered cheating and will result in a grade of zero for the exam. Statement for Academic Integrity: All work in this class is conducted under the Honor Code of Wofford College. Any case of academic dishonesty during an on-line assignment, exam or in the laboratory will be dealt with to the fullest extent of the honor code. Names of Texts and related course materials: T. Engel, and P. J. Reid; Thermodynamics, Statistical Themodynamics and Kinetics; Pearson, Benjamin Cummings; (2005). J. N. Spencer, R. S. Moog, and J. J. Farel; Physical Chemistry: A Guided Inquiry (Thermodynamics); Houghton Mifflin Company; (2004). A non-alpha numeric calculator is required for the final exam.

3 Late work: All work in this course receives a three point per day late penalty. Final Grade: Final grades will be based on the total number of course points accumulated throughout the semester. Skipping a 10-point homework assignment is the same as skipping a 10-point problem on an exam. Based on a percentage of the total course points a grade distribution similar, but not identical, to that given below will constitute the final grade. 100 % 85 % A 85 % 75 % B 75 % 60 % C 60 % 50 % D Below 50 F Learner Outcomes for Thermodynamics: Apply the equations of state (ie. perfect gas, van der Waals and Redlich-Kwong) to determine P,V, or T of a gas. Plot the mathematical functions of thermodynamics utilizing commercial software. Know that energy is conserved during a process (chemical reaction). Know that a reaction is spontaneous when: S universe > 0 or G p, T < 0. Master the manipulation of partial derivatives applied to thermodynamics. Determine the efficiency of a heat engine and a refrigerator. Use Maxwell s equations to convert between the partial quantities of thermodynamics. Describe how an engine turns heat into work in the context of the first and second law of thermodynamics. Use tables of G standard to predict spontaneity. Explain the relationship between chemical potential and phase equilibria. Identify the characteristics of a first order phase transition. Be able to convert Gº at 298 K to other T and p using: dg = Vdp SdT. Know when a reaction will stop and the conditions for equilibrium. Know how to use the phase rule to evaluate multi-component phase diagrams. Construct and interpret single and binary phase diagrams. Calculate state functions and equilibrium constants from electrochemical measurements.
