Chapter , Problem 102AE(choose chapter or problem)
A colored dye compound decomposes to give a colorless product. The original dye absorbs at \(608 \mathrm{~nm}\) and has an extinction coefficient of \(4.7 \times 10^{4} M^{-1} \mathrm{~cm}^{-1}\) at that wavelength. You perform the decomposition reaction in a \(1-\mathrm{cm}\) cuvette in a spectrometer and obtain the following data:
From these data, determine the rate law for the reaction
\(" \text { dye } \rightarrow \text { product" }\) and determine the rate constant.

ANSWER:
Problem 102AEA colored dye compound decomposes to give a colorless product. The original dye absorbs at608 nm and has an extinction coefficient of 4.7 x 10 M cm at that wavelength. You performthe 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 0.545From these data, determine the rate law for the reaction “dye product" and determine the rateconstant. Step-by-step solution Step 1 of 8 The data obtained from spectrometer analysis of dye is as follows: Time (min) Absorbance at 608 nm 0 1.254 30 0.941 60 0.752 90 0.675 120 0.542
