Percent variance for Kc for Fe3+ + SCN- <=> Fe(SCN)2+ = 110%, the average value for kc = 186 Percent variance for Kc for Fe3+ + 2SCN- <=> [Fe(SCN)2+] = 1680%, the average value for kc = 1.10E+06 1a. What does the variance tell you about the relative plausibility of the two possible equilibrium constant expressions? 1b. Suppose you are asked to design an experiment to determine the enthalpy change for the formation of Fe(SCN)2+. How would you go about obtaining a data set that would allow you to determine whether this reaction is endothermic or exothermic? 1c. Comparing the data from parts 1 and 2, briefly explain how your calculations confirm the assumption of one of the proposed reactions but not the other.
