1. Workshop on Equilibrium Overall 1. Given the following data at 298 K, 2NO(g) N2(g) + O2(g) K1 = 1 x 10-30 2NO(g) + Br2(g) 2NOBr(g) K2 = 8 x 101 Calculate Kc for the reaction at 298 K : ½ N2(g) + ½ O2(g) + ½ Br2(g) NOBr. 2.At 25 oC, Kc = 4.66 x 10-3 for N2O4(g) 2NO2(g). If 2.50 g of N2O4 and 0.330 g of NO2 are placed in a 2.00 L reaction vessel, what are the equilibrium concentrations of N2O4 and NO2? 3. Consider the equilibrium reaction P4(g)  2P2(g), where Kp = 0.100 at 1325 K. In an experiment where an initial amount of P4(g) is placed into a container at 1325 K, the equilibrium mixture of P4(g) and P2(g) has a total pressure of 1.00 atm. Calculate the equilibrium partial pressures of P4(g) and P2(g).

2. Workshop on Equilibrium Overall 4. Hemoglobin (abbreviated Hb) is a protein that is responsible for the transport of oxygen in the blood into the lungs. The oxygen binding is pH dependent. The relevant equilibrium reaction is: HbH44+(aq) + 4O2(g) Hb(O2)4(aq) + 4H+(aq) Use Le Châtelier’s Principle to answer the following: a. What form of hemoglobin, HbH44+ or Hb(O2)4, is favored in the lungs? Briefly explain. b. What form of hemoglobin, HbH44+ or Hb(O2)4, is favored in the cells? Briefly explain. c. When a person hyperventilates, the concentration of CO2 in the blood is decreased. How does this affect the oxygen-binding equilibrium? Briefly explain. How does breathing into a paper bag help to counteract this effect? 5. The value of the equilibrium constant in the Haber Process at a certain temperature is 9.1 x 102. If the equilibrium reaction H2(g) + F2(g)  2HF(g) is known to have an equilibrium constant of 3.1 x 102 at the same temperature, determine the value of the equilibrium constant for the reaction N2(g) + 6HF(g)  2NH3(g) + 3F2(g).
