Roshni Sheth, Anne Tolene, and Philip Pearson CH 118-M3 January 27, 2010 Rates of Chemical Reactions 1. Purpose of the Experiment The purpose of the first half of this experiment is to show the relationship between the concentrations in a solution and the rate of the reaction. The second half of the experiment shows the relationship between temperature and the rate of the reaction. The experiment uses iodate and bisulfate at a constant room temperature to determine the order of the reaction with respect to iodate. Once, the concentrations and the times are found the rate constant is determined using the integrated rate law equation. 2. Summary of the Procedure For the Rates of Chemical Reactions experiment, first gather the materials: a well plate, four micropipets, four solutions (IO 3 - , KIO 3 , H 2 SO 3 , and water), a ruler, and a stopwatch. Stretch three of the pipets, to ensure the drops are uniform, and cut at a forty-five degree angle. The forth pipet do not stretch, but draw a line five centimeters from the bottom.
