Reaction Order and Rate Laws—
Student Laboratory Kit
By: The Flinn Staff
How does reactant concentration affect the reaction rate? This relation- ship is expressed in an equation called a rate law. In this laboratory activity, students will perform the reaction between hydrochloric acid and sodium thiosulfate solutions at various reactant concentrations. By monitoring the appearance of the solid product sulfur, the effect of each reactant on the rate will be determined. The data will then be used to determine the order of each reactant and the rate law. Includes reproducible student handouts, detailed background information and complete Instructor’s Notes with sample data, calculations and answers to questions, plus all necessary chemicals and specialized equipment.
Complete for 30 students working in pairs. Fifteen reusable, six-well reaction plates are required and available separately.

St. Joseph’s Prep Seminary, Princeton, NJ
This microscale version of the iodine clock challange will surely spark inquiry-based questions in your lab! Students run and time eight trials simultaneously! The effects of concentration, temperature and a catalyst on the rate of an iodine clock reaction are tested. A starch solution acts as an indicator and produces a dark blue reaction endpoint. All chemi- cals and specialized equipment are provided.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. One timer is required and available separately.
Vitamin C Clock Reaction—Effect
of Concentration on Reaction Rate—
Student Laboratory Kit
By: The Flinn Staff
Your students won’t be “watching the clock” during this class period! Instead, your students will jump at the chance to perform their very own clock reaction experiment using common chemicals. Students mix two colorless solutions of varying concentrations together and watch in amazement as the mixed solution suddenly flashes to blue. How long will it take for the clock to “ring”? Students discover that it depends on the concentration of the reactants! This activity provides a simple, yet dramatic way to introduce the topic of reaction rates and to explore factors that affect the rate. Includes complete instructions with reproduc- ible student handouts, valuable Instructor’s Notes, and all the necessary chemicals for the experiment and the recommended disposal procedure.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
