Kinetics is often considered challenging due to its theoretical and mathematical complexity. Consequently, there is a need for kinetic experiments that are appropriate for chemistry classes. This article presents such experiments using a spiropyran dye and its isomeric merocyanine form. The decolorization reaction of merocyanine to the spiropyran isomer can be analyzed using photometry or nuclear magnetic resonance (NMR) spectroscopy. Photometry is well-suited for determining fundamental kinetic parameters, including the Arrhenius activation energy. While photometry can be implemented in secondary school teaching, ¹H NMR spectroscopy is more appropriate for undergraduate laboratory courses. The latter provides deeper insight into the equilibrium between the spiropyran isomers following UV excitation. Since spiropyran is expensive to purchase, a synthesis suitable for educational settings is also presented. The starting materials are inexpensive, and students can perform the synthesis due to its low hazard potential.
