Rates of Chemical Reactions-The Iodine Clock Reaction
Learners investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...
Curated OER
Experiment on Measuring Reaction Rates
Students investigate the rate of a chemical reaction. For this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...
