Kinetics of a Reaction—AP* Chemistry Classic Laboratory Kit
By: The Flinn Staff
Item #: AP5913
The Kinetics of a Reaction Classic Lab Kit for AP* Chemistry is a two-part microscale lab consisting of a comprehensive, quantitative kinetics activity. Students gain valuable experience with kinetics calculations.
Classic AP requirement 12—Determination of the Rate of a Reaction and Its Order
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.
Complete for 24 students working in pairs. Two reusable 12-well reaction strips are recommended for each student group and may be purchased separately.
