Spectrophotometry and Beer's Law

The video tutorial by Professor Dave explains the study of kinetics, focusing on reaction rates and how to measure them. It introduces spectroscopy as a method to monitor chemical reactions by analyzing light interactions. The tutorial details Beer's Law, which relates absorbance to concentration, and demonstrates its practical application through a calculation example. This approach allows for indirect measurement of reaction rates without halting the reaction.

What is the significance of measuring the intensity of light before and after it passes through a sample?

In the context of the example provided, how would you calculate the concentration of a sample using Beer's law?

How can the absorbance data collected during a reaction help infer the reaction mechanism?
