Product Details

Classic AP requirement #12—Determination of the Rate of a Reaction and Its Order A microscale laboratory consisting of a comprehensive, quantitative kinetics activity. Students study the kinetics of a clock reaction involving the oxidation of iodide ion by bromate ion in the presence of an acid. First, students study the effect of concentration on the rate of reaction to determine the order of reaction for each reactant and the rate constant. Second, the activation energy is determined by varying the temperature, measuring the rate, and calculating the rate constant at the different temperatures. Finally, the effect of a catalyst on the reaction rate is studied. Students gain valuable experience with kinetics calculations. They also understand why the changes in concentration, temperature, and the use of a catalyst are made in each part of the experiment, and how these changes lead to the calculated quantities. Two to three 50-minute periods are required to carry out this experiment-convenient breaking points are given in the teacher notes. Two reusable 12-well reaction strips are recommended for each student group and may be purchased separately. Complete for 24 students working in pairs. Materials Supplied: Copper(II) nitrate solution Hydrochloric acid solution Potassium bromate solution Potassium iodide Sodium thiosulfate solution Starch Beral pipets Cotton swabs ToothpicksFlinn Transition Guide Available! Adapt this classic AP Chemistry experiment for guided-inquiry and correlate with the AP Chemistry curriculum framework with the Flinn Scientific Inquiry Guidance and AP* Chemistry Curriculum Alignment Guide.
