Name_____________________________ Dr. A. H. Martin Chem 114 Quiz 3A February 14, 2008 (All dependent variables x's must be defined for complete credit) (1) 1. Give the K c expression for the equilibrium UO 2 (s) + 4 HF(g) UF 4 (g) + 2 H 2 O(g). Κ χ = [ΥΦ 4 ][Η 2 Ο] 2 [ΗΦ] 4 solids are not included, since this is gaseous water it is included (1) 2. A reaction has an equilibrium constant of 25 at some temperature. If the reactants and product of the equilibrium system are mixed in such a fashion that Q equals50, will the reaction shift toward reactants or products? Justify your answer. Reactants - the reaction will shift to lower Q, this is done by converting products into reactants reducing the P/R ratio. (4) 3. A 2.00 L container is filled with 0.040 mol SO 2 (g) and 0.020 mol O 2 (g). If 0.0290 mol of SO 3 (g) is present when the system come to equilibrium according to the equation 2 SO 2 (g) + O 2 (g) 2 SO 3 (g), calculate K c for the reaction. [SO
