The average k value for the experiment performed during the first week was 584.8/sec*M and 1181/sec*M for the second week. Introduction The objective of this experiment was to have students design a procedure for collecting kinetic data, perform quantitative dilutions accurately, use a spectrometer to observe changes in concentration during a kinetic experiment, and use experimental data to calculate the rate constant of a reaction. This was done by mixing solutions of red dye #40 with solutions of household bleach of different concentrations to determine the change in the rates of reactions. Experimental The procedures for this experiment can be found in the Fundamental Techniques of Chemistry , 6 th edition, author Seven L. Brown, Department of Chemistry, University of Arizona. Materials and Reagents All materials and reagents for this experiment were provided by the University of Arizona....
