Problem Set 5 Answer all the following questions in the order provided. Show all work and units. 1. Calculate K. at 303 K for 50$(8) + Ca(k) = 50Cla(e) if K. = 34.5 at this temperature, 2. Consider the following equilibrium, for which k, = 0.0752 at 480 C 2Cla(s) + 2H2O(g) = 4HCl(g) + O2(g) Determine the values for the following a. 4HCI(g) + O2(E)= 2013(e) + 2H2O(g) b. 6C () + 6H0(8) - 12HCl(g) + 30:48) C2HCl(e) + X 0;() = Cl>() + H2O(g) 3. At 100 C the equilibrium constant for the reaction CoCl:() = Cole) + Ciz(e) has the value K = 2.19x10.Is the following mixture of COCI, CO, and Cl, at 100C at equilibrium? If not, indicate the direction that the reaction must proceed to achieve equilibrium Coch) = 2.00x10*M, (CO) = 3.3 x 10*M, [Cl] = 6.62 x 10M 4. For the equilibrium, Brz(e) + Cu(e) = 2BrCi(e), at 400 K, K = 7.0.16 0.60 mol of Br; and 0.50 mol Cl: are introduced into a 2.0L container at 400 K, what will be the equilibrium concentrations of Brz. Ch, and BrCI? This problem requires an ICE box. This must be clearly shown and filled in properly. 5. For the following reaction, AH = 2816 : 6CO.(g) + 6H2O(l) = CH2O(s) + 60:18) How is the equilibrium yield of CHO affected by: a. Increasing the partial pressure of CO b. Increasing temperature c. Removing Co. d. Decreasing the total pressure e. Adding a catalyst Hint: First determine the direction the equilibrium will shift. If the equilibrium shifts to the reactants the yield of CHO. Will decrease. If the equilibrium shifts to the products the yield of C.H.O. will increase. If no shift occurs the amount of C.H.O. will not be affected
