  • Catalyst | Examples, Definition, Facts | Britannica
    Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions In general, catalytic action is a chemical reaction between the catalyst and a reactant
  • Catalysts - Chemistry LibreTexts
    A catalyst is a substance that speeds up a reaction without being consumed by it More specifically, a catalyst provides an alternative, lower activation energy pathway between reactants and products
  • Catalysis - Wikipedia
    Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst
