Using a spectrophotometer, it is possible to monitor the reaction by measuring the changing concentration of reactant Group 1 or product Group 1 as it progresses. First, the extinction coefficient (8) must be determined for all visībly active species by measuring the Group 3 of each on a spectrophotometer at Group 4 concentrations. These measured values would Group 2 for the reactant and Group 2 for the product as the reaction progresses in accordance with the Beer-Lambert law (A = sbc). Comparing how the concentration of the product changes with respect to the concentration of the reactant would allow for the exponent Group 1 to be determined.
