Chemical Equilibrium—Laboratory Kits
Characteristics of Chemical
Equilibrium—Activity-Stations Kit
By: Patricia Mason, retired, Delphi H.S., Delphi, IN,
and Kathy Kitzmann, Mercy H.S., Farmington Hills, MI
Chemical equilibrium is a balancing act—what happens when the balance is disturbed? In this activity-stations lab, students investigate various reaction conditions that may influence that balance. Four “mini- lab” activities are designed to take about 10 minutes each. Student groups may rotate through the four stations in any order. Each activity focuses on a specific property of chemical equilibrium: The Nature of Equilibrium, Concentration Effect, Temperature Effect, and Effect of Pressure. Includes Instructor’s Notes with complete sample data, comprehensive background information, reproducible student handouts, and all necessary chemicals and consumables. Activity-stations lab format lets you do more labs in less time!
Complete for 24 students working in groups of three. Perform this experiment in a fume hood or well-ventilated lab.

Gas Phase Equilibrium—
Student Laboratory Kit
By: The Flinn Staff
This real-world application kit is just what you need to heighten your students’ interest in equilibrium topics! Provide them with the tools they need to conduct an exciting simulation of smog production and ozone depletion experiments. Introduce microscale techniques to investigate how temperature and pressure affect gas-phase reactions by studying the combination reaction of nitrogen dioxide, a reddish brown gas, to form a colorless dinitrogen tetroxide gas. The gas mixture is safely sealed in a polyethylene pipet bulb and then exposed to changes in temperature and pressure. The color changes will help your students predict the position of the equilibrium changes as the temperature and pressure change. Concepts of Le Chatelier’s principle may be applied to determine whether the reaction is exothermic or endothermic. Includes reproducible student handouts, detailed back- ground information and complete Instructor’s Notes with sample data and answers to all questions.
Complete for 30 students working in pairs.
