This dictionary definitions page includes all the possible meanings, example usage and translations of the word catalyst.
(chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected
something that causes an important event to happen
"the invasion acted as a catalyst to unite the country"
something or someone that causes events to happen with itself being changed.
something that serves as a precipitating occasion for an event; as, the invasion acted as a catalyst to unite the country. A catalyst is never the main cause of an event, but may serve to hasten events for which the underlying causes are present prior to the appearance or occurrence of the catalyst.
A substance that increases the rate of a chemical reaction without being consumed in the process.
Someone or something that encourages progress or change.
Economic development and integration are working as a catalyst for peace.
A catalytic converter.
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. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. 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. Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant, or heterogeneous, whose components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category. Catalysis is ubiquitous in chemical industry of all kinds. Estimates are that 90% of all commercially produced chemical products involve catalysts at some stage in the process of their manufacture. The term "catalyst" is derived from Greek καταλύειν, kataluein, meaning "loosen" or "untie". The concept of catalysis was invented by chemist Elizabeth Fulhame, based on her novel work in oxidation-reduction experiments.
A catalyst is a substance that increases the rate of a chemical reaction by reducing the amount of energy needed to trigger the reaction but remains unchanged itself in the process. It does not alter the products of the reaction, only the speed at which they are produced. Catalysts can be in the form of elements, compounds, or even biological entities, such as enzymes in the human body.
Catalyst is the fourth studio album by American rock band New Found Glory. It was produced by Neal Avron and released on May 18, 2004 through Geffen Records. The album includes an enhanced CD portion with a making of the music video for the inaugural single "All Downhill from Here". Catalyst debuted at a career-high number three on the Billboard 200 chart and was later certified gold by the Recording Industry Association of America on August 18, 2004.
You can describe a person or thing that causes a change or event to happen as a catalyst.a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditions (as at a lower temperature) than otherwise possible;a person or thing that precipitates an event or change; something that makes a chemical reaction happen more quickly without itself being changed;an event or person that causes great change;a person whose talk, enthusiasm, or energy causes others to be more friendly, enthusiastic, or energetic;an agent that provokes or speeds significant change or action;someone or something that causes something to happen or change;Causes,cause,source.

I came legally to america to help the people, but here is what I witnessed as a black man. I see a system of entrapment for blacks which has been set in place for years and has been concretized and solidified in such ways with racism as the driving catalyst, and gate keeper. this makes it almost impossible for blacks to excel-so my reggae sings-no chains around my feet, but still I'm not free? can you imagine people building a system which enslaves them? define freedom in america!
