Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways...

A video lecture that focuses on kinetics, the study of how reactions progress and the rate of reactions. Kinetics, activation energy, activated complex and catalysts are discussed. [15:27]

Enzymes as catalysts for reactions in biological systems; discussion of substrates, active sites, induced fit, and activation energy. [8:12]

This video [7:30] explains how a catalyst speeds up a chemical reaction by lowering the activation energy.
