A catalyst is a substance that increases the rate of reaction by offering an alternative path that lowers the activation energy.
Two types:
- Homogeneous catalysts - the catalyst is in the same phase as the reactants. They work by using their variable oxidation states to oxidise/reduce a reactant, making it more reactive.
- Heterogeneous catalysts - the catalyst is in a different phase to the reactants. They are usually solids, and they provide a surface for the absorption of molecules. The molecules come together in a more advantageous arrangement.
