Kinetics of Dye Decomposition Name__Drew Rasmussen__ Report Form Lab Instructor__Kate Truhler________ Lab Section__Chemistry 112 Lab-011_ Partner’s Name__Andy Zola_________ Date__February 23, 2011 A. Research Questions a. What is the reaction order for crystal violet in its reaction with hydroxide? b. What is the activation energy of the reaction? Rate Constant (k) Temperature (°C) 0.0526 m -1 23.1°C 0.0075 m -1 2.2°C a. Observations: Crystal Violet Solution (CVS) is a very rich purple blue color. There is no apparent smell when wafting. 10.0mL of CVS (2.0x10^-5M) was used for the room temperature reaction. The initial temperature of the CVS was 21.3°C. NaOH is a clear viscous liquid. Has no apparent smell, but when it comes in contact with skin it is very “slimy.” 10.0ml of 0.020M NaOH was used. Adding the NaOH to the CVS began the reaction, and spectrophotometer readings were taken every minute. The purple was becoming less faint as the reaction proceeded. Absorbance was also decreasing considerably as the time went on. For the Iced Bath Reactions, the initial temperature of the CVS was 2.2°C. Approximately 24.9mL of both the NaOH and CVS (same molarities) were used for this reaction since the cuvette would have to be emptied between each reading,
