Reaction Rate and Order

Targets Grades: 10-14
Accommodates 24 Students Working in Groups of 2

Using this superior reagent system, students are able to generate highly reproducible results from an iodine clock reaction. Students determine factors that affect reaction rates as they vary reactant concentrations, measure rates, calculate reaction orders, and calculate reaction rate constants. Activation Energy is also determined utilizing the logarithmic form of the Arrhenius equation by plotting temperature and reaction rate. State of the Art instructor’s manual features background material, easy to follow stepwise protocols, assessment questions, sample data, modeled calculations, and an answer key.  Additional equipment required: stop watch, pipets, lab glassware. Meets AP Science Practices 1, 2 & 4.
