1. catalyst

   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.

1. catalyst

   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.

1. CATALYST

   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.

   Their aim should be to show by 2021, when they gather to take stock of progress made since the Paris agreement and commit themselves to raising their game, that the pandemic has been a catalyst for a breakthrough on the environment.
