This series of simulations progressively extends the dice analogy, letting you explore and visualize situations involving thousands of die with hundred sides.
Before you start you should have a physical intuition of what happens. This can be achieved by following the printed instructions.
This dice-throwing is directly related to chemical kinetics, and at its full expression, chemical equilibrium.
Higher level students will use this as a launching pad to look at orders of reaction as well as activation energy.
The data can be cut-and-pasted into other software for further analysis. Here is a Google Sheet that parses this data, which you can File -> Make a Copy for your own analyses.
