WebCatalysis. Catalysis is the phenomena of altering the velocity of a chemical reaction by the presence of a catalyst. The temperature at which the catalyst activity is maximum is the optimum temp richer. The excess energy that the reactant molecules must acquire to change into the product is the activation energy. It is denoted by Ea. WebMay 1, 2014 · Catalysts are used in many industrial processes, for example in refining petroleum to break long chain hydrocarbon molecules into smaller ones, producing ammonia in the Haber process, and synthesising drugs for the pharmaceutical industry.
