11. Catalyst
    Substance that speeds up a chemical process without actually changing the products of reaction. It lowers the activation energies of both, the forward and the reverse reaction. A catalyst provides a different pathway for a reaction. It may appear in a rate law. A catalyst does not change thermodynam...

12. catalyst
    A substance that participates in a particular chemical reaction and thereby increases its rate but without a net change in the amount of that substance in the system. At the molecular level, the catalyst is used and regenerated during each set of microscopic chemical events leading from a molecular ...

15. Catalyst
    A substance that changes the rate at which a reaction equilibrium is attained, without itself being consumed. Catalysts can increase the rate of reaction (positive catalysts) or decrease them (negative catalysts or inhibitors).

16. catalyst
    catalyze; catalysis. A substance that increases the rate of a chemical reaction, without being consumed or produced by the reaction. Catalysts speed both the forward and reverse reactions, without changing the position of equilibrium. Enzymes are catalysts for many biochemical reactions.

17. catalyst
    Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalyst that have the same phase as the reactants are homogenous catalysts (e.g. enzymes in biochemical reactions). Those that have a different phase are heterogeneous cat...
