Construction of a Multichannel UV-Vis Spectrophotometer

The book provides a brief history of spectrophotometry and presents the construction of a multichannel UV-Vis spectrophotometer. It then explores the application of the equipment in the kinetic analysis of the oxidation reaction of potassium permanganate in a basic medium, providing important calculations such as rate constants, activation energy, enthalpy variation, entropy variation, and Gibbs free energy variation.Through the application of the spectrophotometer, the equipment has proven to be an excellent tool for teaching chemistry, providing a wealth of fundamental chemical concepts that are explored in detail.
