  5. DOE Explains...Catalysts | Department of Energy

    Catalysis is the process of adding a catalyst to facilitate a reaction. During a chemical reaction, the bonds between the atoms in molecules are broken, rearranged, and rebuilt, recombining the atoms …

  6. What is Catalysis? - American Chemical Society

    In chemistry, catalysis refers to changing the speed of a reaction using a substance that’s not consumed by the reaction.

  7. Catalytic Reaction (Catalysis): Definition, Types, & Mechanism

    Catalytic reaction or catalysis is the process that alters the rate of a chemical reaction under the influence of a catalyst. A catalyst is a chemical substance added to a reaction to either accelerate or …

  8. Catalysis - an overview | ScienceDirect Topics

    Catalysis is defined as the process of modifying the rate of a chemical reaction, typically accelerating it, by adding a substance that is not consumed in the reaction.

  9. 12.10: Catalysis - Chemistry LibreTexts

    Dec 9, 2025 · Catalysts affect the rate of a chemical reaction by altering its mechanism to provide a lower activation energy. Catalysts can be homogenous (in the same phase as the reactants) or …

  10. Catalysis – Chemistry

    Part of the rate of formation lost by operating at lower temperatures can be recovered by using a catalyst. The net effect of the catalyst on the reaction is to cause equilibrium to be reached more …
