CHEMISTRY 2002 NAME PROBLEM SET #33: Equilibrium Review DATE PERIOD Review Chapter 18 1. Remember that only species whose concentrations can change (gases or aqueous solutions) appear in the equilibrium constant expression. Write the algebraic form of the equilibrium constant for each of the following reactions: a. 2 C 5 H 6 ( g ) C 10 H 12 ( g ) K eq = b. 2 N 2 O 5 ( aq ) 4 NO 2 ( aq ) + O 2 ( g ) K eq = c. 2 NaHCO 3 ( s ) 2 Na 2 CO 3 ( s ) + CO 2 ( g ) + H 2 O ( g ) K eq = 2. Consider the reaction: 2 O 3 ( g ) 3 O 2 ( g ) H = –284 kJ Predict the effect on the equilibrium (shift to left, shift to right, or no effect) of each of the following changes: a. increasing the volume of the container

Suggest four ways to increase the concentration of SO 3 in the following equilibrium reaction: SO 2 ( g ) + ½ O 2 ( g ) SO 3 ( g ) + 23 kcal a. b. c. d. 4. What is the concentration of H + ( aq ) in an aqueous solution in which [OH – ] = 1.0 x 10 –3 M? Is this solution acidic or basic? 5. If the pH of a solution is 5, what is [H + ]? Is the solution acidic or basic? ← → ← → ← → ← → ← →...
