a. The Clausius-Clapeyron equation.
b. Molarity, molality, mole fraction, and weight percent.
c. Raoult’s Law.
d. Colligative properties.
e. Chemical kinetics.
f. Chemical equilibrium.
g. Electrochemistry.
2. Recognize zero, first, and second order reactions.
3. Discuss the molecular basis of chemical kinetics.
4. Write expressions for both homogeneous and also heterogeneous equilibria.
5. State the significance of a K equilibrium value as to extent of a chemical reaction.
6. Predict shifts in the position of equilibrium using Le Chatelier’s Principle.
7. Classify acids and bases in Bronsted and Lewis Theories.
8. Discuss acid/base strength using Ka values and use the pH scale to relate hydronium and hydroxide concentrations.
9. Discuss and solve problems involving titration, buffers, and the hydrolysis of ions.
10. Predict whether a precipitate will form when two solutions are mixed and solve K problems.
11. Understand and relate enthalpy, entropy, and free energy as they relate to chemical reactions and equilibrium.
12. Discuss the working of both the voltaic and electrochemical cells and solve problems involving them.
