MHS AP Chemistry
Syllabus 15

 Read Chapter 15 Section 15-1 The Concept of Equilibrium Know How equilibrium ties in with rates & reverse reactions Read "Chemistry at Work" on page 562. How about that Haber guy? Section 15-2 The Equilibrium Constant Equilibrium expression, "Law of Mass Action" Equilibrium constant Kc vs. Kp magnitude of K, "right-" and "left-" favored reactions Kp = Kc(RT)Dn Kf = 1/Kr Section 15-3 Section 15.3 - Heterogeneous Equilibria What is Kc for H2O(l) Û H+(aq) + OH–(aq)? Section 15-4 Calculating Equilibrium Constants In Class ex. 15.7 In Class ex. 15.8 Section 15-5 Applications of The Equilibrium Constant Q (reaction quotient) Section 15-6 le Chatlier's Principle Problems 15.8, 15.10, 15.12, 15.16ab 15.20, 15.22a, 15.24, 15.30, 15.36 15.44 15.50, 15.71 Lab 25 Determination of an Equilibrium Constant [MHS AP Chem page]

Now for some questions...

For the reaction    2SO3(g) Û O2(g) + 2SO2(g)    Kc = 0.119 M.

1. What would be the value of Kc for the reaction        4SO3(g) Û 2O2(g) + 4SO2(g)
2. What would be the value of Kc for the reaction        O2(g) + 2SO2(g) Û 2SO3(g)
