Reduction of Methylene Blue

Written by Allison Guindon The rate constant of the reduction of methylene blue was determined by spectroscopy. The experimental koverall was determined to be 9.4±4.2L2/mol2/s at 295.15K. The experimental value was compared to the known value of 5.0L2/mol2/s resulting in a percent error of 88%. Sources of error include, not mixing the solutions and placing them into the spectrometer fast enough, or fingerprints on the cuvette. BACKGROUND: Reaction rate constants (k) measure the speed of chemical reactions. Reaction rates depend […]
