Second question: given the chemical recation:

cu+2(aq) + 2cl-1(aq) --> cucl2 (s)

which of the following statements best defines the common ion effect?
a. when a chemical reaction has reached equilibrium and we add more of one of the ions that already exists in the solution, the forward reaction will proceed at a faster rate, and the equilibrium will be reestablished.
b. when a chemical reaction has reached equilibrium and we add more of one of the ions that already exists in the solution, the reverse reaction will proceed at a slower rate, and the equilibrium will be reestablished.
c. when a chemical reaction has reached equilibrium and we add more of one of the ions that already exists in the solution, the reverse reaction will proceed at a faster rate, and the equilibrium will not be reestablished.
d. when a chemical reaction has reached equilibrium and we add more of one of the ions that already exists in the solution, the reverse reaction will proceed at a faster rate, and the equilibrium will be reestablished.
