Unformatted text preview: affect the product’s concentration measured because absorbance and concentration are directly related in Beer’s Law. Therefore, a change in absorbance would provide a different value for C (concentration). These absorbance values were used to calculate the concentration of the product Fe(SCN) 2 in order to determine the concentrations of each species at equilibrium. Using the concentration of the product, the concentrations of the reactants at equilibrium are found using an ICE chart. With these concentrations, the solutions for the value, K, can be calculated with the equation for equilibrium. Specifically, the average value of K found was 92.99, a relatively large value for K. When K is large, this means that at equilibrium, the concentration is mostly in the products of the equation, in this case the product is Fe(SCN) 2 ....
