What is the spectrophotometric determination of K in equilibrium?
The equilibrium constant, K, for a chemical system is the ratio of product concentrations to reactant concentrations at equilibrium, each raised to the power of their respective stoichiometric coefficients. Measurement of K involves determination of these concentrations for systems in chemical equilibrium.How can we determine the equilibrium constant for a chemical reaction lab?
The numerical value of an equilibrium constant is obtained by letting a single reaction proceed to equilibrium and then measuring the concentrations of each substance involved in that reaction. The ratio of the product concentrations to reactant concentrations is calculated.What is the purpose of the determination of an equilibrium constant lab?
The equilibrium constant, K, is used to quantify the equilibrium state. The expression for the equilibrium constant for a reaction is determined by examining the balanced chemical equation.- By spectroscopy and Beer's Law, it is found that [FeSCN2+] at equilibrium is 1.50 x 10-4 M.
