Course Learning Objectives

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

  1. Pure species phase equilibrium:
    Describe the role of Gibbs energy in determining pure species phase equilibrium.  
    Apply the Clapeyron equation to relate T and P between two states of a pure species in phase equilibrium. State when you can simplify the Clapeyron equation to the Clausius-Clapeyron equation.
    [CBEE 211 & ChE 311] Apply the first law to systems which undergo a phase change.
  2. Thermodynamics of mixtures:
    Apply thermodynamics to mixtures by defining and finding values for pure species properties, total solution properties, partial molar properties, and property changes of mixing.
    Explain enthalpy and entropy of mixing in physical terms.
  3. Fugacity
    Explain how fugacity relates to partial molar Gibbs energy (chemical potential) and why we use it.
    Define fugacity. Explain the role of the reference state (and that T0=T)
  4. Fugacity in the vapor phase: 
    Calculate fugacity and fugacity coefficient for a pure species i using tables, EOS, and generalized correlations.  Identify appropriate data and reference state
    Calculate fugacity and fugacity coefficient for a species i in a mixture using EOS
    Describe the Lewis and ideal gas approximations for fugacity of i in a mixture. Provide physical explanations for the fugacity coefficient
  5. Fugacity in the liquid phase:
    Explain why we choose the ideal solution as a reference state for a liquid. Explain the molecular origin and calculate reference fugacities based on the Lewis/Randall and Henry’s reference states. Identify the "shift" in curves of ln(gamma,i).
    Identify when like or unlike interactions are stronger. Know when the Lewis/Randall reference state equals the saturation pressure and how to correct when it does not.
    Define gE and explain why we use it. Given a model for gE determing an expression for gamma,i. Calculate gamma,i.
  6. Phase Equilibrium:
    Solve phase equilibria problems for Vapor-Liquid equilibria (VLE), Liquid-Liquid equilibria (LLE).
    Identify and solve problems for systems containing azeotropes (VLE) and partially miscible solutions (LLE). Explain what causes each.
    Describe how phase diagrams are constructed. When given any phase diagram, an overall composition, and T or P determine what phase or phases are present. When two phases are present determine their composition and how many total moles are in each phase.
  7. Chemical Reaction Equilibrium:
    Distinguish between reaction rate and reaction equilibrium in a chemically reacting system
    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 a single reaction or multiple chemical reactions in a single phase or for heterogeneous reactions
