You prepare a reaction by mixing 4.89mL of 0.00200 M Fe3+, 3.08mL of 0.00200 M SCN-, and 1.98mL of water. The reaction reaches equilibrium as well as the absorbance is found to be 0.352 using a spectrophotometer. If the proportionality constant between absorbance as well as concentration of FeSCN2+ is known to be 3553, compute the equilibrium constant for the reaction.
