###### Problem Details

Consider the following reaction:
Fe3+(aq) + SCN-(aq) ⇌ FeSCN2+(aq)
A solution is made containing an initial [Fe3+] of 1.1 x 10-3M an initial [SCN-] of 7.8 x 10-4M. At equilibrium, [FeSCN2+] = 1.7 x 10-4M.

A) Kc = 2.0 x 102

B) Kc = 3 x 10-2

C) Kc = 3.3 x 10-3

D) Kc = 3.0 x 102

E) Kc = 5.0 x 10-3
