Question

The correct interpretation of the equation below is:
Fe3+(aq) + SCN–(aq) --> and <-- FeSCN2+(aq)

A. A heterogeneous equilibrium exists because of the charged ions.
B. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.
C. The equilibrium constant is Kc = [Fe3+][SCN–]/[FeSCN2+]
D. The reaction is incomplete because the product is still charged.
E. None of these.

Answer 1

Is the problem written as you have it posted or is it written as
Fe3 + SCN^- <-->FeSCN^+2 (with aq after each of course)
At any rate, I think the answer is B.
Check them out. A heterogeneous equilibrium is one in which there are two phases. Here all are the same phase; i.e., in solution.
B. that is a true statement.
C. The equilibrium constant for the reaction is the reciprocal of that shown.
D. Many reactions carry a charge. Of course the charges must balance with the same number on the product side as the reactant side.

Answer 2

Sorry, it is <-->, there was an error when I typed up the problem. Thank you for your help!
