1. Write the equilibrium constant expression for the following reaction: H3PO4(aq) + 3 H2O(l) ↔ PO4 3- (aq) + 3 H3O+ (aq)
2. (LeChatlier’s principle) The following reaction has Kc = 4.2 x 102 at 325oC, all gases. PBr3 + Cl2 ↔ PCl3 + Br2 ΔHo = -47 kJ/mol
a. For this reaction at equilibrium, [PBr3] = [Cl2] = 0.0273 M, and [PCl3] = [Br2] = 0.560 M. What do you expect to happen to the equilibrium concentrations of each species (increase, decrease, stay the same) if the temperature of the reaction is raised to 450oC ?
b. the system is at equilibrium, and dichlorine (Cl2) is added to the reaction. What is the effect on the concentrations of PBr3, PCl3, and Br2.
c. what is the effect of adding helium (He) gas to the reaction at equilibrium. What is the effect on the concentrations of PBr3, PCl3, Cl2, and Br2.
