Chemical Reactions General Theory of Catalysis

Chanical catalysis is an area of tremendous interest because of its occurrence in reactions important to both biochemical, biotechnological, and industrial processes. The word catalysis (katalyse) was coined by Berzelius in 1835. In his words, Catalysts are substances, which by their mere presence evoke chemical reactions that would not otherwise take place. [Pg.89]

The statement that a catalyst cannot change the magnitude of an equilibrium constant is correct only if (1) the forward and backward reactions of an equilibrium process follow strictly the same mechanism, i.e., forward and backward reactions must involve the same transition states (if there is one or more than [Pg.89]
