Modeling the Rate of Heterogeneous Reactions
... Assumptions on reaction schemes (kinetic models) provide correlations between surface coverages of intermediates and the external variables. Improved kinetic models could be developed when atomic processes on surfaces and the identification and characterization of surface species became available. H ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
