Catalysts

Mr. Anderson's Chemistry Essentials video 044 covers catalysts, explaining how they speed up reactions by lowering activation energy without being consumed. The video includes a demonstration of the elephant toothpaste experiment and a catalase enzyme reaction with hydrogen peroxide. It discusses how catalysts stabilize transition states and create new intermediates, altering reaction mechanisms. The video concludes with a summary of energy profiles and the role of catalysts in chemical reactions.

Describe the elephant toothpaste demonstration and its significance in understanding catalysts.

What is the primary function of a catalyst in a chemical reaction?

How do catalysts lower the activation energy of a reaction?

Explain the role of catalase in the breakdown of hydrogen peroxide.

What happens to the energy profile of a reaction when a catalyst is introduced?
