In Lab Experiment 2, you studied the following equilibrium: Fe3+(aq) + SCN–(aq) ⇌ Fe(SCN)2+(aq) If you knew the equilibrium constant K and the initial concentrations of Fe3+(aq) and SCN–(aq), what would be the simplest way to determine the equilibrium concentration of Fe(SCN)2+(aq)? A. By writing the equilibrium constant equation and solving it for [Fe(SCN)2+]equ. B. By measuring the absorbance of the equilibrium samples and using the Beer–Lambert law. C. By ensuring that SCN– is not in excess relative to Fe3+(aq). D. [Fe(SCN)2+]equ is always equal to the initial concentration of SCN–. E. By plotting the absorbance of Fe(SCN)2+(aq) versus concentration and determining the slope.
