Catalyst Types
Quick fact
Catalysts can be solids, liquids, or gases, but they always remain unchanged after a reaction.
Why this is interesting
Did you know that your body uses tiny helpers called enzymes to speed up digestion? These are just one type of catalyst, and there are many more!

Understanding Catalyst Types
Catalysts are substances that help reactions happen faster without being used up. They come in different types based on how they work with the chemicals involved. Some are in the same phase as the reactants, while others exist in a different one. This helps them interact more effectively during the process.
A deeper explanation
Catalysts lower the energy needed for reactions to occur by providing an alternative pathway. Homogeneous catalysts mix with reactants in the same phase, whereas heterogeneous ones are in a different state, like solids in liquids. Enzymes, a type of biological catalyst, demonstrate how nature uses these principles to make life possible.
