Part A.) If a beaker were prepared with 5.00 ml of Fe³⁺ and 5.00 ml of 0.10 M HNO₃ and had an absorbance of 0.016, what would the K_eq of this mixture be? Why?

Part B.) Use the mean value that you determined for K_eq to calculate the SCN^- concentration in a solution whose initial Fe³⁺ concentration is 4.00 x 10^-2 M and initial SCN^- concentration is 1.00 x 10^-3 M.

Part C.) What is your % error based on the accepted value of the equilibrium constant?
