Beer’s Law Extinction Coefficient
chem question? I need help with this please?
extinction coefficients are usually reported to the wavelength of maximum absorbance. Dating the extinction coefficient at an absorbance max and know the thickness of the layer, c, can determine the concentration of the sample, measuring its aborbance, A, to the fullest absorbance. Explain how this is done using the Beer Act.
Beer law states that absorbance is directly proportional to the concentration of a solution. If you plot absorbance and concentration, the resulting graph gives a straight line. The equation for the straight line (called regression line) can be used to determine the concentration of an unknown solution once the percentage of transmittance (% T) was measured.
