Catalysis
Catalysis is the acceleration of a chemical reaction by a substance — the catalyst — that provides an alternative lower-energy pathway and is regenerated unchanged at the end of each reaction cycle.
Overview
Catalysts increase reaction rates by lowering activation energy, enabling reactions to proceed faster or under milder conditions than otherwise possible. A small quantity of catalyst can drive transformation of vastly larger amounts of substrate because it is not consumed — this distinguishes catalysis from ordinary reagent participation.
Why it matters
The influence of catalysis on civilization is profound: the Haber-Bosch process for synthesizing ammonia underpins nitrogen fertilizers that sustain roughly half the world's food supply, while an estimated 90% of all commercially produced chemical products involve a catalytic step. Catalytic converters have dramatically reduced toxic automotive emissions at global scale, and catalytic asymmetric synthesis enables production of enantiomerically pure pharmaceuticals critical to patient safety.
