Unformatted text preview: Emily Bissel MS #1116 Lab Partners: Becca Angell and Megan Anders February 26, 2008 Tuesday PM Lab 5: Spectrophotometric Determination of an Equilibrium Constant Introduction When the rates of the forward and reverse of a reaction equal one another, the reaction is said to be at chemical equilibrium. The point at which this occurs can be represented by the equilibrium constant, K eq . By examining the equilibrium constant, a person can determine whether the reaction favors the products or the reactants. If the K eq is a larger number, the reaction tends to move to the right, and favors the products; if K eq is a small number, the reaction tends to move to the left, and therefore favors the reactants. K eq varies with temperature, but remains a constant at a constant temperature. Because of this, K eq can be determined through experimentation because it should be the same no matter what the initial concentrations of the reactants and products are. In this experiment, the initial concentrations of the reactant will be known. However, in order to determine the amount of product formed, a the reactant will be known....
