LeChatelier’s principle states, “When a change is made to an equilibrium system, the system moves to counteract the imposed change and restore the system to equilibrium.” Use your observations from part 2 to answer the following questions:

Explain in terms of LeChatelier’s principle the observations made when KSCN was added to the system (Was the forward or reverse reaction favored?
Explain in terms of LeChatelier’s principle the observations made when NaCl was added to the system (Was the forward or reverse reaction favored? )
Explain in terms of LeChatelier’s principle the observations made when silver nitrate was added to the system(Was the forward or reverse reaction favored?)
Explain in terms of LeChatelier’s principle the observations made when Fe(NO3)3 was added to the system(Was the forward or reverse reaction favored? What happened to the reactants or products as a result of adding ?).
Explain in terms of LeChatelier’s principle and your observations upon the addition of heat to and removal of heat from the system (Was this reaction endothermic or exothermic? Was heat a reactant or product of this reaction?).

Add 0.1M KSCN drop wise until change is
observed
*increases concentration of SCN in the system
Add 4.0M NaCl drop wise until change is
observed
*decreases concentration of Fe³+ in the system
Add 0.1M Fe(NO3)3 drop wise until change is
observed
*increases concentration of Fe³+ in the system
Add 0.05M AgNO, drop wise until change is
observed
*decreases concentration of SCN' in the
system
Place in hot water bath for 1-2 minutes
*adds heat to the reaction system
Place in ice water bath for 1-2 minutes
*removes heat from the reaction system
