1. When applied to an equilibrium system, which of the following stresses would cause a change in the Ko value after the equilibrium has been re-established? a. Addition of catalyst b. Decrease in temperature by cooling the system c. Addition of an inert gas to increase the pressure d. Decade in concentration by removing a product Explanation: 2. The equation that is represented by the equilibrium law expression a. 2NO2(g) 2NO(g) + O2(g) b. 2NO(g) + O2(g) +2NO2(g) Explanation: KC [NO. [NO(a)][O2(g)] is C. NO2(g) NO(g) + O2(g) d. NO(g) + O2(g) NO2(0) Use the following information to answer the next question. The equilibrium law expression for an industrial method of producing ethanol is shown below. Kc= [C₂HOH [C2H4(g)] [H2O(g)] Under certain conditions, Kc = 300.0. At equilibrium, a 5000L reaction vessel contains 115 mol of C₂Hand 110 mol of H2O(g). 3. Under these conditions, the equilibrium concentration of C2H5OH() is a. 1.60x10 mol/L b. 1.52x101mol/L Calculations: c. 7.50x10¹mol/L d. 5.92x10 mol/L 4. In Agl) Ag* (aq) + (aq), the equilibrium constant is 1.0x10-16. Calculate the concentration of Ag* (aq) and I(aq) at equilibrium. Record your answer as a.bx10°. Calculations: 1.
