Catalysis

Catalysis is the rate of change of a chemical reaction using a catalyst. A catalyst is unique, as it is not consumed by the chemical reaction itself, allowing for other chemical reactions to be done with one catalyst. A catalyst participating in the speed up of a reaction is called a positive catalysts. Catalysts that slow the chemical reaction are called inhibitors, or negative catalysts. There are four types of catalysis: Heterogeneous, homogeneous, electocatalysts, and organocatalysts. Heterogeneous catalysts usually are solids acting on liquids or gases. Homogeneous catalysts are usually dissolved in the solvent. Electrocatalysts are solely correlated with electricity. Oganocatalysts deal with carbon and carbon based molecules.
