Elephant's Toothpaste

The video explains how catalysts can speed up chemical reactions, using the example of hydrogen peroxide breakdown in the Elephant's Toothpaste experiment. It discusses the concept of activation energy and how catalysts lower this energy, allowing more molecules to react. The video also covers the use of catalytic converters in cars to reduce harmful emissions by converting gases into less harmful substances.

What is the role of a catalyst in a chemical reaction?

Describe the process of the experiment involving hydrogen peroxide and potassium iodide.

What are the products of the breakdown of hydrogen peroxide?

Explain the significance of the food coloring and detergent in the experiment.

What happens to the activation energy when a catalyst is added?

What visual effect is created when the foam from the reaction comes into contact with food coloring?

How do catalytic converters in modern cars help reduce harmful emissions?
