Science Buddies: Can You Change the Rate of a Chemical Reaction?
The ingredients in Alka-Seltzer tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces...
Concord Consortium
Concord Consortium: Chemical Reactions and Stoichiometry
In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...
Simon Fraser University
Chem1 Virtual Textbook: Chemical Kinetics and Dynamics
Understand the rates and mechanisms of chemical change. These topics stand in contrast to the subjects of equilibrium and thermodynamics that control the direction of chemical change.

Science Buddies: How Fast Does an Alka Seltzer Tablet Make Gas?
This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer tablets are plopped into water. You'll track the volume of carbon dioxide gas produced at regular intervals after the...
