Catalysts & Fine Particle In Industry Catalyst: Catalysis, alteration of the speed of a chemical reaction, through the presence of an additional substance, known as a catalyst, that remains chemically unchanged by the reaction. Enzymes, which are among the most powerful catalysts, play an essential role in living organisms, where they accelerate reactions that otherwise would require temperatures that would destroy most of the organic matter. A catalyst in a solution with-or in the same phase …showed first 75 words of 1324 total…
