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.)

  • $\begingroup$ Is this supposed to model Briggs-Rauscher? If so, what corresponds to A, B, D, E, X and Y in the wiki article? $\endgroup$ – octopus Jun 19 '17 at 16:17

    $\begingroup$ See this for detail. It contains all you need to solve your problem. $\endgroup$ – Todd Minehardt Jun 19 '17 at 16:18
  • $\begingroup$ @IvanNeretin Brusselator is too simple. $\endgroup$ – Mithoron Jun 19 '17 at 21:42
