Catalysis is defined within chemical kinetics and thermodynamics by the phenomenon where a substance alters reaction rates without undergoing net consumption in the overall process. This abstract theory relies on the formal definition that catalysts function by providing an alternative reaction pathway with a lower activation energy, thereby increasing collision efficiency while preserving their original state at the conclusion of the sequence. The concept operates exclusively within the domain of physical chemistry, specifically as a fundamental mechanism distinguishing itself from reactants and intermediates through conservation of mass relative to specific cycles rather than bulk stoichiometric change.
