demonstrative kinetics experiment

I'm looking for a good kinetics experiment to run in the lab section of our graduate lab course. It should be a reaction that we can set up on a bench with inexpensive materials, that will take place safely in an NMR tube, and should take about one to five hours to complete at room temperature. (If done in one, then the students can witness the outcome; more than that, and they'll just set it up, watch the first few minutes of it, then leave and get the data later.) We can follow it using any high-sensitivity high-natural abundance nucleus: 1H, 19F, or 31P being preferred.

Any suggestions?

Thanks.
