The organic compound 18-crown-6 (see preceding problem) also binds strongly with the alkali metal ions in
methanol: K++18-crown-6⇄[complex]+. In methanol solution, the equilibrium constant is 1.41*106.
A similar rxn with Cs+ has an equilibrium constant of only 2.75*104. A solution is made (in methanol) containing 0.020mol/L each of K+ and Cs+. It also contains 0.30mol/L of 18-crown-6. Compute the equilibrium concentrations of both the uncomplexed K+ and the uncomplexed Cs+.
