###### Question:

2. Consider the following equilibrium: Cu2+(aq) pale blue + 4NH3(aq) +[Cu(NH3)4]2+ (aq) colorless deep purple Would you expect to see an increase, no change, or a decrease in the purple color when: (a) the temperature of the system is increased (the reaction is endothermic). (b) a catalyst is added. (c) more aqueous NH3 is added to the equilibrium. (d) the pressure is increased. NaOH(aq) is added to the system, resulting in the precipitation of Cu(OH)2(s). _(1) (f) the volume of the system is increased.
