# Catalyst and Inhibitors home experiments

My teacher assigned me a science experience involving catalysts and inhibitors at home.

I think I understand the principle of it, but I fail to find possible experiments that I can do at home with a thermostat and some home substances.

The experience:

3 reactions... 1 with the catalyst, 1 with the inhibitor, 1 without anything.

I will compare them by measuring the reaction speed with a factor (preferably the heat variation).

EDIT: I can also measure the volume of the product.

Thank you.

You might look up the decomposition of hydrogen peroxide, $$\ce{H2O2}$$. The 3% solution sold as antiseptic should be safe to use at home, as would be some readily available catalysts and inhibitors.
You can have fun burning things (carefully) in the evolved $$\ce{O2}$$, too.
