2. Using the data below, calculate the specific and molar extinction coefficients of the product of the photometric reaction in solution in terms of the analyte. Do the required quantities change if we change the wavelength of light, the concentration of the substance (within the concentration range for which the basic law of light absorption is satisfied), and the thickness of the absorbing layer?
Substance to be determined Reagent Reaction product λ, Substance concentration l, A
