The Effect of Concentration on Reaction Rate

This java applet (and accompanying material) is designed to simulate an experiment to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide. In the experiment, the learner takes readings and plots graphs within the Java applet. The simulation is designed to complement practical laboratory experiments and to provide an opportunity to repeat experiments for revision purposes. This material was developed in the United Kingdom for students in their final year of school and first year of University. This simulation should be useful in the teaching of reaction rate kinetics. Additional information can be obtained from The materials come with extensive help documentation and are available as simple SCORM Content Packages from Other simulations developed as part of the same program will be made available through Merlot soon. In the meantime, please leave feedback. As we are not US based, it would be especially helpful if users could provide advice on the exact educational level thse would be taught at in US educational establishments.
