Catalysis in industry

Catalysis in industry. Catalysts are substances that speed up reactions by providing an alternative pathway for the breaking and making of bonds. Key to this alternative pathway is a lower activation energy than that required for the uncatalysed reaction. Catalysts are often specific for one particular reaction and this is particularly so for ...
