Prerequisites: CHEN 205, MATH 308, and CHEN 320 (or registration therein)
Skill Prerequisites : You are expected to have the ability to:

Know the first and second law of thermodynamics and the concepts of internal energy, work, entropy, enthalpy, and free energy

Write mass and energy balances of non-reactive systems

Solve quadratic and cubic equations

Know how to differentiate and integrate functions

Use computer software for linear and nonlinear algebraic equations, and linear and nonlinear regression.
Course Outcomes: By the end of the course, you should be able to apply phase and reaction equilibrium concepts to chemical engineering problems, specifically
:
 Solve phase equilibrium problems. Understand the concepts of chemical potential and fugacity. Select appropriate models for calculating phase equilibria of specific gas, liquid and solid mixtures. Calculate bubble point pressure; bubble point temperature; dew point pressure; dew point temperature; flash calculations.
Interpret experimental data and select appropriate models to describe thermodynamics of mixtures with multiple phases. Apply phase equilibrium concepts to engineering problems.
 Work effectively in teams. Work effectively in homework assignment teams and develop problem solving skills.
Exams: There will be three non-cumulative exams during the term and a cumulative final exam. Exam I is scheduled on September 28 th
, Monday; Exam II on October 26 th

Americans with Disabilities Act (ADA) Statement
The Americans with Disabilities Act (ADA) is a federal antidiscrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact the Department of Student Life, Services for Students with Disabilities in Cain Hall, Rm. B118, or call

Academic Integrity Statement
“An Aggie does not lie, cheat, or steal or tolerate those who do.”
As commonly defined, plagiarism consists of passing off one’s own the ideas, work, writings, etc., which belong to another. In accordance with this definition, you are committing plagiarism if you copy the work of another person and turn it in as your own, even if you should have the permission of that person. Plagiarism is one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which research cannot be safely communicated. If you have questions regarding plagiarism, please consult the latest issue of the Texas A&M University Student Rules, under the section “Scholastic Dishonesty”. Please see the Honor Council Rules and Procedures on the web at http://www.tamu.edu/aggiehonor.
