A catalyst is a material that, without being consumed by the process, speeds up a chemical reaction or decreases the temperature or pressure required to initiate one.
The addition of a catalyst to a reaction is known as catalysis.
A catalyst is a material that influences, encourages, or speeds up the reaction of two or more components to produce an alternative end result.
In industrial operations, including the production of food, catalysts are frequently utilized to maximize production rates and quantities.
