Catalysis vs. Catalyst — What's the Difference?

Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it.

A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change

The acceleration of a chemical reaction by a catalyst.

(Chemistry) A substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.

The action of a catalyst, especially an increase in the rate of a chemical reaction.

One that precipitates a process or event, especially without being involved in or changed by the consequences

(chemistry) The increase of the rate of a chemical reaction, induced by a catalyst.

(chemistry) A substance that increases the rate of a chemical reaction without being consumed in the process.

Dissolution; degeneration; decay.

Something that encourages progress or change.

A process by which a chemical reaction is accelerated in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of enzymes (as diastase, or ptyalin) on starch.

(literature) An inciting incident that sets the successive conflict into motion.

Acceleration of a chemical reaction induced the presence of material that is chemically unchanged at the end of the reaction;

(automotive) A catalytic converter.

(fantasy) An object that facilitates the casting of a spell (such as a magic wand).

A substance that initiates or accelerates a chemical reaction without itself being affected; as, thousands of enzymes serve in concert as calaysts to produce the sequence of reactions we call "life"; the industrial production of cheap ammonia depended on finding a good catalyst.

Something that serves as a precipitating occasion for an event; as, the invasion acted as a catalyst to unite the country.

Something or someone that causes events to happen with itself being changed.

(chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected

Something that causes an important event to happen;
