I want to use the Briggs-Rauscher experiment to demonstrate oscillating reactions, and then explain it using a numerical model. How much is known about this reaction? Is it possible to write down a set of differential equations for the concentrations of each chemical, and solve it to find oscillatory behaviour?
If so, what is a fairly simple but realistic set of differential equations for Briggs-Rauscher, and what are good parameters to find oscillations?
(By fairly simple I mean that it could be handled in an Excel spreadsheet or similar by talented school students.)
