Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant....
a. Estimate the equlibrium concentration of the FeSCN2+ ion in this equilibrium mixture. b. Calculate the Keq value for this mixture. I got keq = -47/25000, but I have no idea if that's correct. I really don't even know where to start on the equilibrium concentration. I thought it...
Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]...

You will then measure the absorbance of a series of samples to determine the concentration of FeSCN2+. This data will enable you to determine the equilibrium constant for the reaction (equation 2).OceanOptics SpectrophotometersAtkinsJones
What is the numerical value of the equilibrium constant, Kc, for the following equilibrium: Fe3+(aq) + SCN-(aq) gives FeSCN2+(aq), given the initial concentrations of (Fe3+) = 0.590 M, (SCN-) = 1.239 M, and an equilibrium concentration ...
