Solution:
A colored dye compound decomposes to give a colorless product. The original dye absorbs at 608 nm and has an extinction coefficient of 4.7 104 M-1 cm-1 at that wavelength. You perform the decomposition reaction in a 1-cm cuvette in a spectrometer and obtain the following data:
Time (min) Absorbance at 608 nm
0 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".
