2.The reaction that took place is exothermic. I know the reaction that took place is exothermicbecause when the reaction was placed in the ice bath the absorbance went up indicatingthat it went to the products, this also indicated that the reaction was exothermic and notendothermic.3.The effects of adding and removing reactants to and from the equilibrium mixture is thatwhen adding Fe(NO3)3it created more reactants and made more products. On the otherhand when adding the EDTA to the solution it binded to the reaction making less reactantsand therefore less products.
1Evidence1.La Chatelier’s Principle states that when a variable affecting the state of a system ischanged, the equilibrium of the system will be modified so as to compensate for thechange in the variable. I found that Kcof this reaction at room temperature is183.325 I found this by finding the concentrations the FeSCN2+, Fe3+, and SCN-. Byfinding this I was able to solve for the equilibrium constant, Kc.
