### Chemical Equilibrium: Hydrogen Sulfide and Lead(II) Ions Reaction **Equation and Reaction Description:** Hydrogen sulfide gas (\(H_2S\)) bubbled into an aqueous solution of lead(II) ions produces lead sulfide precipitate and hydrogen ions. This reaction is described with the following equation: \[ H_2S(g) + Pb^{2+}(aq) \rightleftharpoons PbS(s) + 2H^+(aq) \] **Task:** Choose the correct equilibrium constant expression for this reaction. **Options:** - \(\mathbf{K = \dfrac{[\mathrm{H}^+]^2}{[\mathrm{H_2S}][\mathrm{Pb^{2+}}]}}\) - \(\mathbf{K = \dfrac{[\mathrm{PbS}][\mathrm{H^+}]^2}{[\mathrm{H_2S}][\mathrm{Pb^{2+}}]}}\) - \(\mathbf{K = \dfrac{([\mathrm{PbS}]([\mathrm{Pb^{2+}}])}{([\mathrm{H_2S}])}}\) - \(\mathbf{K = \dfrac{\mathrm{[H^+]}^2}{[\mathrm{H_2S}][\mathrm{Pb^{2+}}]}}\) - \(\mathbf{K = \dfrac{(P_{\mathrm{H_2S}})([\mathrm{Pb^{2+}}])}{[\mathrm{H^+]}^2}}\) **Note:** The equilibrium constant (\(K\)) is defined as a ratio of the concentration of the products to the concentration of the reactants, each raised to the power of their respective coefficients in the balanced equation. Solid substances (PbS(s) in this case) are not included in the expression. **Submission Section:** To finalize your selection, click the "Submit" button. **Navigation:** - To review your selection, click "Submit Answer." - To explore another set of questions, click "Try Another Version." - There are options to go to the "Previous" or "Next" parts of the problem set. ### Example Analysis: Given the options, look for the expression that matches the known form for equilibrium constants excluding solids and incorporating gaseous and aqueous species appropriately. ### User Interface: Within the
