Unformatted text preview: Experiment 7 Kinetics: Oxidation of Organic Dye Monitored by Laser Absorption Amy Corcoran and Jamie Gates New Jersey Institute of Technology CHEM 339- Physical & Analytical Lab for ChE Lab Completed: April 5, 2011 Lab Submitted: May 5, 2011 Abstract: In this experiment, a food color dye (methylene blue) within water undergoes an initial oxidation step with the help of a reaction with bleach (sodium hypochlorite). Laser light absorption serves as the reaction diagnostic. The initial part of the experiment (Part A) required water at 21 degrees Celsius. In part A, there were two runs executed. The first run required 100 milliliters of bleach with a drop of methylene blue dye. The second run required 200 milliliters of bleach with a drop of methylene blue dye. In the second part of the experiment (Part B), water was boiled to 38 degrees Celsius. In part B, the first run required 100 milliliters of bleach with a drop of methylene blue dye. The second run required 200 milliliters of bleach with a drop of methylene blue dye. From the data, the average k(T) value of the reaction at 21 degrees Celsius is-4.1206 x 10^(-4), and the average k(T) at 38 degrees Celsius is -9.38322014 x 10^-4....
