WebMany catalytic processes are known in which the catalyst and the reactants are not present in the same phase—that is, state of matter. These are known as heterogeneous … WebCatalysts increase the rate of reaction by providing an alternative pathway which has a lower activation energy; Catalysts can be either homogeneous or heterogeneous; Homogeneous catalysts are those that are in the same phase as the reaction mixture; For example, in the esterification of ethanoic acid (CH 3 COOH) with ethanol (CH 3 CH 2 …
WebHomogeneous catalysis refers to reactions where the catalyst is in the same phase as the reactants, principally in solution. In contrast, heterogeneous catalysis describes processes where the catalysts and substrate are in distinct phases, typically solid-gas, respectively.
