Consider the following equation: [Ni(H2O)6]2+ + 6NH3 <----> [Ni(NH3)6]2+ +6H2O The effects of stress on this equilibrium can be monitored by changes in color. An equilibrium mixture is blue-green (indicating both products and reactants are present). a.) When the equilibrium mixture is heated, the color changes to bright green. Which direction has the reaction shifted? To the products, the reactants, or no shift? How did you determine this? Which is the exothermic direction of this reaction? Forward, reverse, or cannot tell? b.) When a few drops of concentrated NH3 are added to the equilibrium mixture, the solution turns deep blue. Which direction has the reaction shifted? To the products, the reactants, or no shift? How did you determine this? c.) Addition of concentrated HNO3 to the blue-green mixture will remove NH3 by reaction. What should happen to the color of the solution? Will it turn more blue, turn more green, or no change? Explain.
