2.      Apply the Clapeyron equation to relate P and T for a pure species in phase equilibrium.

3.      Apply thermodynamics to mixtures by defining and finding values for pure species properties, total solution properties, partial molar properties, and property changes in mixing.

4.      Relate partial molar properties by the Gibbs-Duhem equation.

5.      Evaluate fugacity and fugacity coefficient of pure gases and gases in mixtures using equations of state, generalized correlations and P-V-T data.

6.      Distinguish between the reference states defined by the Lewis-Randall rule and Henry’s law for ideal solutions.

7.      Treat non-ideality by finding activity coefficients through correlative and predictive models.

8.      Solve phase equilibrium problems for vapour-liquid equilibria (VLE), liquid-liquid equilibria (LLE) and solid-liquid equilibria (SLE).

9.      Identify systems with azeotropes in VLE.

10.  Use thermochemical data to calculate the equilibrium constant for a chemical reaction. Calculate equilibrium constant at different temperatures.

11.  Determine the equilibrium composition for a chemical reaction in gas phase.

12.  Determine the equilibrium composition for a system with multiple reactions.

13.  Apply phase rule for chemically reacting systems and solve problems involving heterogeneous chemical reaction equilibria.

14.  Practice teamwork by forming and working in study groups.

15.  Improve communication skills by submitting concisely and effectively written homework solutions individually or in teams.

16.  Improve communication skills by listening, thinking and talking during the classroom discussion of the course material and in active sessions.
