The equilibrium constant experiment explores the relationship between the concentration of reactants and products in a chemical system. It focuses on the formation of the thiocyanatoiron(III) complex, where iron(III) ions react with thiocyanate ions. This experiment is designed for chemistry students studying equilibrium concepts and spectrophotometric analysis. Students will determine the equilibrium constant, Kc, by measuring absorbance at 447 nm and constructing a calibration curve. The experiment emphasizes the importance of concentration and light absorption in equilibrium systems.
