Question
19. Oxygen (O2) and ozone (O3) form an equilibrium mixture according to the reaction: 3 02 (g) = 2 O3 (g) At equilibrium, you measure the partial pressure of the O2 to be 1.2 atm and the partial pressure of O3 to be 0.44 atm, What is the value for Kp of this reaction? A) 0.37 B) 2.7 C) 0.059 D) 0.11 20. Sulfur trioxide decomposes according to the reaction: 2 SO3 (g) = 2 SO2 (g) + O2 (g) A 1.0 L flask is filled with 1.3 mol SO3, 1.0 mol SO2, and 0.20 mol O2 and allowed to reach equilibrium. If the temperature is chosen so that Kc = 0.0050, how will the reaction shift to reach equilibrium? A) towards the products because Q > Kc B) towards the products because Q< Kc C) towards the reactants because Q > Kc D) towards the reactants because Q< Kc 21. According to the Bronsted-Lowry acid base theory, a base is: A) anything that gives up OH- in solution. B) a proton donor C) a proton acceptor D) an electron pair acceptor
