Exam 1 - Learning Outcomes
The following are the learning outcomes that match up with Exam 1. When we write exam questions we try our best to match them up with learning outcomes. If we do this with what is listed below and have one question per outcome, then we will have 18 questions. You should expect at least 20 questions though and no more than 25.
Unit 5
- Demonstrate mastery of reaction stoichiometry
- Predict the sign of ΔG, ΔH, and/or ΔS for physical change
- Interpret heating curves and calculate heat required for phase transitions and temperature changes
- Describe phase transitions (macroscopically and microscopically) as well as differentiate between boiling and evaporation
- Understand how intermolecular forces, temperature, and solute concentration affect vapor pressure.
- Interpret phase diagrams and identify normal boiling and melting point, critical point, and triple point.
- Describe the factors that favor the dissolution process in terms of intermolecular forces and thermodynamics (enthalpies of solution, hydration, lattice energy, entropies of solution, free energy of solution….)
- Describe how T and P (Henry’s Law) each affect solubility .
- Define and perform calculations for common concentration units molarity, molality, and mole fraction.
- Perform calculations and discuss the concepts of the 4 colligative properties: Vapor Pressure, Boiling Point change, Melting Point change, Osmotic Pressure.
11-17. Skip these for now, they will return for Exam 3.
Unit 6
- Describe the relationship between free energy and equilibrium
- Convert ΔG to K and vice versa.
- Write the mass action expression for homogeneous and heterogeneous equilibria.
- Determine new values for K when combining multiple reactions.
- Determine if a system is at equilibrium and if not which direction the reaction will shift to achieve equilibrium.
- Calculate the concentration of all species at equilibrium.
- Know the difference between Kp and Kc and be able to convert between the two.
- Set up and solve a RICE table.
