One of your experiments involved the determination of the equilibrium constant for the reaction Fe3+(aq) + SCN-(aq) = (FeSCN)2+(aq) ( = being equilibrium) A student pipetted 10.00mL of 2.50x10-3mol/L iron (III) nitrate solution and then 2.00mL of 2.50x10-3mol/L NaSCN solution into a 25mL volumetric flask and added water up to the mark. From the absorbance of the solution, the concentration of (FeSCN)2+ was found to be 3.46x10-5mol/L. Calculate the value of the equilibrium constant for this reaction.
