G C E K? Use the provided ICE tables to determine K, values for your reaction mixtures. (1) Fill in the initial reactant concentrations in line "I". You already calculated the initial concentrations of your reactants for your pre-lab, and [[FeSCN]"]=OM 11 (2) Fill in equilibrium concentrations of [FeSCN]2 in line "E". You already calculated [[FeSCN)] from your calibration curve (3) Fill in line "C" for changes in concentration using "x" as a placeholder for actual values. (4) Use your knowledge of changes in [[FeSCN]2] to determine the value of x. Remember...line !+ line C= line E (5) Substitute your value for x to determine equilibrium concentrations of [Fe³] and [SCN'].
