Question

13) At 200Â°C, the equilibrium constant (Kp) for the conversion of NO to oxygen and nitrogen gas is 2.40 x 10^3. A closed vessel is charged with 36 atm of NO. At equilibrium, the partial pressure of O2 is atm. 14) At elevated temperatures, molecular hydrogen and molecular bromine react to partially form hydrogen bromide: H2 (g) + Br2 (g) -> 2HBr (g) A mixture of 0.682 mol of H2 and 0.440 mol of Br2 is combined in a reaction vessel with a volume of 2.00 L. At equilibrium at 700 K, there are 0.546 mol of H2 present. At equilibrium, there are mol of Br2 present in the reaction vessel. 15) What is the pH of a solution prepared by mixing 25.00 mL of 0.10 M CH3CO2H with 2500 mL of 0.050 M CH3CO2Na? Assume that the volumes of the solutions are additive and that Ka = 1.8 x 10^-5 for CH3CO2H.
