Chem 145 section B, March 3, 2015 Abstract: One of the objectives of this experiment are to determine the kinetic order of a reaction from dependence of the rate on reactant concentrations. The method of completing this experiment is to run ten trials total and manipulate the amount of hydrogen peroxide and potassium iodine. For four trials H2O2 stayed constant and the KI was manipulated from the original amount and decreased by 25% each trial. The second four trials the exact opposite was done with KI and H2O2. Each trial runs for a total of 400 seconds. When both the KI and H2O2 were manipulated both final concentrations decreased.

Introduction: Chemistry deals with change and this experiment is to determine and understand how rapidly a chemical reaction occurs. In this experiment potassium iodine and hydrogen peroxide are used. Hydrogen peroxide is an important oxidizing agent in the industry where it is used to bleach paper pulp, textiles and leather. Potassium iodine is used as catalysts in this experiment. Catalysts can speed up a decomposition reaction. They increase the rate of a reaction without undergoing a net change. The change in pressure will determined by the LabQuest. The objectives of this experiment are to monitor the rate of the chemical reaction, determine kinetic order of a reaction from the dependence of the…
