               Use the chapter study guides that are posted on the class website as
               guidelines.
Coverage:      Pages 160-203 and 222-224 in your Lecture Notebook.

               Chapters 16     all assigned material
               Chapter 17      all assigned material
               Chapter 18,     Pages 770-779 in textbook

Information Provided on the Exam:
1. A periodic table
2. Solubility rules as on page 168 of lecture notes
3. Ksp, Kf, Hfo, Gfo and So values if needed
4. R = 8.314 J/mol K R = 0.0821 L atm/K mol
   ΔSsurr = - ΔHsys/T          ΔGo = -RTlnK            ΔG = ΔGo + RTlnQ

 Suniv = Ssys + Ssurr     ln K2 =    -   H     1 -    1
                                K1           R     T2     T1

Make sure you know:
1. ΔG = ΔH - TΔS        G, ΔH, ΔS = products - reactants (*each mult. by # moles)
2. Either the formulas used in the vapor pressure and normal boiling point problems
   or how to derive them from ΔGo = -RTlnK ΔG = ΔH - TΔS

DO NOT PROGRAM ANYTHING INTO YOUR CALCULATOR!!!!
DO NOT BRING ANY NOTECARDS TO THE EXAM!!!!!
