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 February 22, Monday; Exam II on March 23,
Wednesday, and Exam III on April 20, Wednesday. All the exams will be in class in JEB
112. The final exam is scheduled on May 9, Monday, from 8am to 10am.
Homework: Homework will be assigned once a week and it is due on class, one week
after the day when it is assigned.

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

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
