An aqueous solution was prepared at 21 oC by mixing 7.00 mL 2.00 x 10-2mol L-1Fe3+, 2.00 mL 1.50 x 10-3 mol L-1SCN−, and 1.00 mL water. At equilibrium, the concentration of the product complex, [Fe(SCN)2+]eq was determined to be 1.74 x 10-4mol L-1. What is the value of the equilibrium constant K for the reaction of interest at 21 oC?
