  1. Lon-Capa • 3rd HW assignment due Monday, 9/19, 5 pm. • 2nd Quiz due Monday, 9/19 by 10 pm. It will open today at 5 pm. • For the quiz, use K = °C + 273.2

  2. Exam I • Thursday, September 22, 7:00-9:00 pm; rooms are on the website. • Conflict: (9/22) 4:30-6:30pm in 165 Noyes Lab; sign up in 367 NL • Conflict with conflict? Email me right away. • Review sessions: • Monday (9/19): 217 Noyes Lab from 5-6 pm • Tuesday (9/20): 166 Bevier Hall from 7-8 PM

  3. Exam I • Practice exam posted by this evening with equation sheet. • Take when you feel ready for the exam. • Take as an actual exam (not just more practice problems)

  4. K is a Constant (at given T)

  5. Heterogeneous Equilibria

  6. Clicker Question For which of the following reactions does K = Kp at the same temperature? a) 2H2(g) + O2(g) 2H2O(g) b) 2KClO3(s) 2KCl(s) + 3O2(g) c) CO(g) + H2O(l) CO2(g) + H2(g) d) 3Fe(s) + 4H2O(g) Fe3O4(s) + 4H2(g)

  7. Clicker Question For this question, use the balanced equation N2(g) + 3H2(g) 2NH3(g). You have three steel tanks each containing mixtures of N2(g), H2(g), and NH3(g) at the same temperature. The conditions in the tanks are: Tank 1: [N2] = 2.00 M [H2] = 3.00 M [NH3] = 6.00 M Tank 2: [N2] = 2.00 M [H2] = 4.00 M [NH3] = 7.00 M Tank 3: [N2] = 3.00 M [H2] = 2.00 M [NH3] = 4.00 M Two of the tanks have reach equilibrium. Which tank has not reached equilibrium, and which direction must the reaction proceed in order for that system to reach equilibrium? a) Tank 1 has not reached equilibrium; the reaction in tank 1 must proceed to the left in order to reach equilibrium. b) Tank 1 has not reached equilibrium; the reaction in tank 1 must proceed to the right in order to reach equilibrium. c) Tank 2 has not reached equilibrium; the reaction in tank 2 must proceed to the left in order to reach equilibrium. d) Tank 2 has not reached equilibrium; the reaction in tank 2 must proceed to the right in order to reach equilibrium. e) Tank 3 has not reached equilibrium; the reaction in tank 3 must proceed to the left in order to reach equilibrium.

  8. Reaction Quotient (Q)
