Solution

Solution Steps

Step 1: Identify the Reactants and Products

The given reaction is: \[ \left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightleftharpoons\left(\mathrm{CH}_{3}\right)_{3} \mathrm{NH}^{+}(\mathrm{aq})+\mathrm{OH}^{-}(\mathrm{aq}) \]

Step 2: Write the Equilibrium Constant Expression

The equilibrium constant expression, $ K $, for a reaction is given by the ratio of the product of the concentrations of the products to the product of the concentrations of the reactants, each raised to the power of their respective coefficients in the balanced equation.

For the reaction: \[ \left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightleftharpoons\left(\mathrm{CH}_{3}\right)_{3} \mathrm{NH}^{+}(\mathrm{aq})+\mathrm{OH}^{-}(\mathrm{aq}) \]

The equilibrium constant expression is: \[ K = \frac{[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{NH}^{+}][\mathrm{OH}^{-}]}{[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}]} \]

Step 3: Simplify the Expression

Since $\mathrm{H}_{2} \mathrm{O}(\mathrm{l})$ is a pure liquid, its concentration is constant and does not appear in the equilibrium constant expression.
