Catalysts Definition Catalysts increase reaction rates without getting used up Explanation They do this by providing an alternative route or mechanism with a lower activation energy Comparison of the activation energies for an uncatalysed reaction and for the same reaction with a catalyst present If the activation energy is lower, more particles will have energy >1 Chemistry A substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process 2Video shows what heterogeneous catalysis means Catalysis in which the catalyst is present in a separate phase; Heterogeneous And Homogeneous Catalysis For The Hydrogenation Of Carboxylic Acid Derivatives History Advances And Future Directions Chemical Society Reviews Rsc Publishing Heterogeneous catalysis meaning
