Introduction: Dynamic equilibriums are reactions in which reactants form products at the same rate products decompose to the original reactants such that the moles of each constituent remain constant over time. Le Chatelier’s Principal explains the mechanics of dynamic equilibriums by using the theme of equilibrium in every sense. In regards to the molar composition of the system, the ratio of reactants to products remains constant in the form of Equation (5). This means if one side of the equilibrium sees a flux of concentration, the system automatically balances itself to reach the ratio. When heat is added to the system, it will shift to the endothermic side, and conversely, if heat is taken away, the system will shift to the exothermic. Lastly, upon adding pressure, the system will shift to the side with the least amount of molecules, and again, conversely with a decrease in pressure. Experiment: The reaction of Iron(III) Nitrate and Thiocyanide yields Ferrothiocyanide , a dark orange colored liquid. The objective of the lab is to measure the amount of Ferrothiocyanide produced during the reaction through a colorimeter. By increasing the concentration of the Iron(III) Nitrate to a super high amount compared to the rest, the equilibrium will shift to the opposite side and all of the Thiocyanide will be used to yield Ferrothiocyanide; that is, for every mole of Thiocyanide used, a mole of Ferrothiocyanide was made . Using varying amounts of Thiocyanide would yield different amounts for Ferrothiocyanide which would be detected by a colorimeter. Seven different solutions were prepared with varying concentrations of thiocyanide. Each
