2. When making the calibration curve in Part 1 of the experiment, it was assumed that the reaction mixture went to completion. That is, you assumed that [SCN] = [FeNCS2+]eq when the [Fe3+]o was in large excess. Using your average Keq (Part 2), calculate the equilibrium concentrations of each species in the last mixture (2mL Fe3+ and 225μL SCN-) of Part 1. a. [Fe3+]eq (M) b. [SCN]eq (M) c. [FeNCS²+]eq (M)
