WebAug 15, 2024 · Aug 15, 2024. Catalysis is the ability of some species to rapidly speed up the rate at which a chemical reaction proceeds. For historical reasons, the discipline is normally split into two categories; homogeneous and heterogeneous. Homogeneous catalysis is concerned with catalysts that are in the same phase as the chemical …
WebAug 21, 2024 · A catalyst introduces a completely different pathway/mechanism that was inaccessible before. Some reactions simply cannot proceed without a catalyst; the energy barrier is too high. This may be true even if the overall reaction is exergonic ( Δ G) and thus thermodynamically favored to proceed.
