Text:  Phase Equilibrium in Chemical Engineering, Stanley M. Walas, 1985.

Prerequisites:  CHE 151 or equivalent, Math 133a or equivalent,

Web Supplements:

• Course Green Sheet

• Lecture Notes

• Homework and Exam Solutions

Purpose of Course:  Qualitative development of fundamental laws of

thermodynamics and their application to chemical processes.  Equilibria

and thermal effects in homogeneous and heterogeneous systems.  Studies

of behavior of complex mixtures and high pressure phenomena.

Topics:  1st and 2nd Law, Fugacity and Activity, Reactive Process, Special topics including interfacial and surface phenomena, and supercritical fluids.

The good student strives not for easy answers, but for genuine understanding, persevering in the face of obstacles.  The good student wishes not just to "get it done," but to "get it right"; not simply to "get ahead," but to "get the most out of it."

Course Policies:

• Material covered during class will build upon reading assignments.  Hence, students are expected to attend the lectures.
• You are encouraged to study together, but your grade will depend on your own mastering of the material. 
• Drop policy:  Friday, February 11 is the last day to drop this class without a petition.  Petitions will not be approved for the following reasons:  Taking too many units; missing prerequisites; poor advising; low grade in this class.
• A course grade of incomplete will be given in the most compelling non-academic circumstance, which must be documented in writing and approved by me no later than 24 hours before the scheduled final examination date.
• Exam scores and course grades will not be given over the phone, as this is a violation of confidentiality.
• Final Exam Monday May 20, 1715-1930

Grading:

            homework                 10%

            midterm                     30%

            paper                          30%

            final                             30%

           total                       100%

Exams:

• The midterm and final exams are open book, open notebook.
• Students must show complete solutions and write legibly to receive credit for a problem.
• Cases of academic dishonesty will result in an F on the exam, and a note to appropriate personnel on campus, including your advisor for addition to your file, and may result in an F in this course.  Please review the College of Engineering Academic Dishonesty code, as that will be followed in this course.
• If you must miss an exam due to emergency, notify me as soon as possible.  If possible, notify me prior to the exam.  If you cannot reach me personally, a message may be left on my answering machine (office phone) indicating your name and the reason for your absence.  I reserve the right to require a doctor's excuse, where applicable.  You may or may not be able to take a make-up exam.
• You are encouraged to arrive on time for exams.  If you are late, come anyway.  If you do not attend the exam and have not been excused, you may not have the opportunity to take a make-up.

Paper:

• To facilitate further development of a particular topic of your own interest, a project paper will be due on Monday, November 24.  The paper is an individual assignment and is not intended to be done in a group. Students are encouraged to study a paper related to their thesis project.
• An article from one of the following journals is to be chosen:  Journal of Chemical Thermodynamics, Fluid-Phase Equilibria, Journal of Non-Equilibrium Thermodynamics, Chemical Engineering Science, AIChE Journal, Journal of Supercritical Fluids, Colloid and Interface Science.  The article should be a research paper and not a review, letter or short communication type of paper.  You should give a copy of your paper to the instructor by February 18.  After that you cannot change your mind about the paper, so be sure to read the paper through prior to that date and if need by, choose a different paper to suit your interests properly.
• The purpose of the paper is to do a critical review of the paper.  You will need to read the paper and enough of the references listed at the back of the paper to appropriately describe the background to the work.  The final paper should contain the following sections: 
1. Introduction (describes the purpose of the research and summarizes the work undertaken by the researchers)
2. Background (includes the necessary theoretical information to explain the work)
3. Critical Review (Review the work as if you were a reviewer of the work.  You should explain why the research described in the paper is (or is not) unique, significant, worthy of publication, and adequately completed.  You should also explain if the appropriate experiments were carried out and if the data has been accurately represented.  If the work is entirely theoretical, you should explain whether the theory is soundly based in thermodynamics and if it can be realistically applied to real systems.)
4. Conclusion (In one paragraph explain the main reasons why the paper should or should not be published.)
5. List of References  Be sure to cite your references.  Do not use web pages as sources of technical information, but if for some reason you use the internet, be sure to cite the pages you have used.
• The paper should NOT INCLUDE figures, tables or other representations of actual data.  You can refer to the figure or table number in your text.
• Plagiarism will not be tolerated. 
1. You cannot copy any published text verbatim, with the exception of spoken words - which should be set in from the text and the name of the speaker should be provided.  There is not likely any opportunity in this paper for such a reference.
2. Paraphasing whole sentences or sections of text is not acceptable.  You should read the entire paper, outline your thoughts and write your own paper.
3. If you have any doubts as to whether something is plagiarism, please ask the instructor before turning in the final paper. 
4. Plagiarism will result in an F on the paper, administrative disciplinary action and possibly, and F in the course.
• The paper should be 15 pages maximum length spaced 1.5. 
• Papers will be turned back to the author and not graded that have more than 3 grammatical mistakes.  If English is not your first language, you should get help in the 90W lab or other resource to edit your paper before turning  it in for a grade.  If your paper is turned back, the maximum score will be dropped by 10% and for every subsequent rejection, the maximum score will be dropped by an additional10%.

Course Schedule

Course learning objectives:

2.  Use equations of state to estimate properties of pure substances and mixtures:

• densities of liquid and vapor phases
• vapor pressures
• critical properties of mixtures
• vapor-liquid equilibrium relations
• deviation of enthalpy from ideality
• deviation of entropy from ideality

3.  Analyze the thermodynamic consistency of experimental data using the Gibbs-Duhem relation

4.  Identify conditions of phase equilibria for systems of pure components or multicomponent systems

• vapor-liquid
• liquid-liquid
• solid-liquid

5.  Identify conditions of chemical equilibria for multicomponent systems

• pure gas

6.  Estimate the solubilities of solids and liquids in supercritical fluids  

7.  Analyze surface and interfacial properties to identify the impact of surface area on bulk equilibrium properties.
