Multiple-choice questions may continue on the next column or page find all choices before answering. Constants R = 8 . 314 J K 1 mol 1 Definitions Q [C] c [D] d [A] a [B] b Equations G = H- T S G =- RT ln K ln K 2 K 1 = H R parenleftbigg 1 T 1- 1 T 2 parenrightbigg Q = K [at equil.] K w = [H + ][OH ] 001 5.0 points The reaction Ag + ( aq ) + Cl ( aq ) AgCl(s) has an equilibrium of 10 20 (K eq = 10 20 ). If you have a beaker containing 1 liter of wa- ter with 0.1 mol of AgCl(s) in it along with 10 6 M Ag + ( aq ) and 10 15 M Cl ( aq ), how does the reaction shift? 1. left correct 2. not at all 3. not enough information 4. right Explanation: Q = 1 [Ag + ] [Cl ] = 1 10 6 10 15 = 10 21 Because Q is greater than K, the reaction will shift to the left....
