Question
Use the following reaction to answer the questions below. Assume that the reaction is at equilibrium before anything is added. CoCI_4^2-(aq) + 6 H_2O(g) doubleheadarrow Co(H_2O)_6^2+(aq) + 4 CI^-(aq) Write the K_c for the reaction. For the following questions, answer toward reactants or toward products. If NaCI is added, how will the equilibrium position change? If the reaction is exothermic, what will happen if the reaction vessel is placed in an ice bath? What will happen to the equilibrium position if Na_2CoCI_4 is added to the solution? What will happen to the equilibrium position if Ag^+ ions are added to the equilibrium?Explanation / Answer
1) [Co(H2O)+2] [Cl -]4
Kc = -------------------------
[CoCl4 -2] [H2O]6
2) towards reactants
3)towards products(assuming forward reaction is exothermic)
4)towards products
5)towards products
