Table LC.3: Equilibrium Response for Iron Thiocyanate Reaction Analysis of equilibrium response to various stressors Test tube 1: Reference Test tube 2: Added KSCN(aq) Test tube 3: Added Fe(NO3)3(aq) Test tube 4: Added NaF(s) Test tube 5: Hot water bath Test tube 6: Ice bath Normal A D Color observation T " Y 82 orange more red/brown than reference more red/brown than reference less red/brown than reference less red/brown than reference more red/brown than reference Table view 1 List view Reaction response 1. For test tubes 2 through 6, explain how each change affected the equilibrium in terms how each change affected the value of Qe or Ke and how this is consistent with your observation. Choose Towards products For Tubes 2, 3 and 4 include in your analysis what happens chemically when each reagent is added. State the direction in which the equilibrium shifts and relate how the change in solution color supports your conclusions.
