1. For the reaction given below, 2.00 moles of A and 3.00 moles of B are placed in a 6.00-L container. A(g) + 2B(g) C(g) At equilibrium, the concentration of A is 0.300 mol/L. What is the concentration of B at equilibrium? 0.300 mol/L 0.433 mol/L 0.500 mol/L 0.600 mol/L 2. Which of the following is a conjugate acid/base pair? HCl/OCl- H2SO4/SO42- NH4+/NH3 H3O+/OH- 3. A 10.0-g sample of solid NH4Cl is heated in a 5.00-L container to 900°C. At equilibrium the pressure of NH3(g) is 1.20 atm. NH4Cl(s) NH3(g) + HCl(g) The equilibrium constant, Kp, for the reaction is: 1.20 1.44 2.40 31.0 None of these 4. The following reaction is investigated (assume an ideal gas mixture):

2N2O(g) + N2H4(g) 3N2(g) + 2H2O(g) Initially there are 0.10 moles of N2O and 0.25 moles of N2H4 in a 10.0-L container. If there are 0.06 moles of N2O at equilibrium, how many moles of N2 are present at equilibrium? 0.9 0.04 0.06 0.02 None of these 5. The reaction quotient for a system is 7.2 x 102. If the equilibrium constant for the
