Rates of reactions

Science presenter Jon Chase briefly outlines collision theory and then describes four ways to increase the rate of a reaction. The effect of concentration is demonstrated using an iodine clock reaction. The effect of temperature is demonstrated using a glowstick. The effect of a catalyst is demonstrated using hydrogen peroxide and manganese(IV) oxide. The effect of particle size is demonstrated using the combustion of sugar.
