Introduction to Catalysts and Investigating Catalytic Activity with Hydrogen Peroxide Decomposition
This video provides an explanation of what a catalyst is and how it can increase the rate of chemical reactions. The concept of activation energy is introduced, and it is explained that catalysts lower activation energy, allowing more...

Allylic/Benzylic Bromination With N-Bromo Succinimide (NBS)
We've learned about radical bromination for alkanes, but there is another method of radical bromination that can be applied to allylic and benzylic systems. This utilizes the reagent NBS, and it can be a useful synthetic technique. Let's...

How Enzymes Denature
Enzymes have optimal conditions under which they operate. Temperature, pH, enzyme concentration and substrate concentration are some conditions that affect the rate of reaction. As enzymes are proteins, they have an optimum temperature...
