Spectrоphоtоmetry is used to determine the equilibrium constаnt for the reаction, Fe3+ + SCN- à [FeSCN]2+ by meаsuring the “redness” of the iron thiocyanate complex. Given the information provided, calculate the equilibrium constant, Kc, for this reaction. [Fe3+]initial = 2.00 x 10-3 M [SCN-]initial = {th} x 10-4 M Absorbance (A) at 477 nm for [FeSCN]2+ = 0.64 Answer format: Enter the value of Kc in standard (not scientific) notation using 3 SF.
