A colored dye compound decomposes to give a colorless product. The original dye absorbs at 608 nm and has an extinction coefficient of 4.7 x 10* M-'cm¬1 at that wave- length. You perform the decomposition reaction in a 1-cm cuvette in a spectrometer and obtain the following data: Time (min) Absorbance at 608 nm 1.254 30 0.941 60 0.752 90 0.672 120 0.545 From these data, determine the rate law for the reaction "dye - product" and determine the rate constant.
