Old Exams

Old exams are avaiilable here for you to practice:

Exam 1 2016

Exam 1 from 2016 is available on the link above.  One point of note.  The emphasis on which content we are covering is quite different this year, so the exam emphasis will also change.

ChE 312 had 3 exams  in 2016 - so the timing was different relative to content. Both exams 2 and 3 are posted below.

          Exam 2 2016

Exam 3 2016


Lecture Handouts

Lecture handouts will be archived here in PDF format.


Course Learning Objectives

By the end of this course, you will be able to:

  1. Describe the role of Gibbs energy in determining pure species phase equilibrium. Apply the Clapeyron equation to relate T and P for a pure species in phase equilibrium.
  2. Apply thermodynamics to mixtures by defining and finding values for pure species properties, total solution properties, partial molar properties, and property changes of mixing. Apply the Gibbs-Duhem equation to relate partial molar properties.
  3. Find the fugacity and fugacity coefficient of pure gases and gases in mixtures using tables, equations of state, and general correlations.
  4. For liquids and solids, identify Lewis/Randall and Henry’s Law reference states for ideal solutions. Correct the reference states for pressure. Solve for non-ideality by determining activity coefficients through models for excess Gibbs energy, gE.
  5. Solve phase equilibria problems for Vapor-Liquid equilibria (VLE) , Liquid-Liquid equilibria (LLE), vapor - liquid - liquid equilibria (VLLE) and Solid-Liquid equilibria (SLE). Identify and solve problems for systems containing azeotropes (VLE) and partially miscible solutions (LLE).
  6. Use thermochemical data to determine the equilibrium composition for a chemical reaction. Calculate the equilibrium constant at different temperatures. Determine the equilibrium composition for a system with multiple chemical reactions.
