Pronunciation: [kˈatɐlˌa͡ɪzd] (IPA) 
The word "catalysed" is spelled with a "y" instead of an "i" in the middle because of its suffix "-yzed" which comes from the Greek word "zūmós". The IPA transcription of "catalysed" is /ˈkætəlaɪzd/. The "c" is pronounced as "k", the "a" as "æ", "t" as "t", "ə" as a schwa sound, "l" as "l", "y" as "ai", "z" as "z", and "d" as "d". It means that the word is pronounced as "cat-tuh-lyzed".
Catalysed, also spelled "catalyzed," is the past tense and past participle form of the verb "catalyze." The term "catalyse" is derived from the noun "catalyst" and refers to the process or action of accelerating or facilitating a chemical reaction.
In a general sense, "catalysed" describes the phenomenon where a substance, known as a catalyst, promotes and speeds up the rate of a chemical reaction, without undergoing any permanent changes or getting consumed during the process. A catalyst essentially lowers the activation energy required for a reaction to occur, leading to an increased reaction rate and thus, achieving the desired outcome more efficiently.
When an action or event is said to be "catalysed," it implies that a catalyst played a crucial role in initiating or enhancing the process, effectively propelling it forward. This could include instances where the catalyst enables the conversion of reactants into products, the transformation of molecular structures, or the breaking down of complex substances into simpler components.
The concept of catalysis is widely applicable in various fields, including chemistry, biochemistry, and industry. Catalysis not only enables the synthesis of new compounds, but it also enhances the efficiency of industrial processes, reduces energy consumption, and aids in the development of sustainable technologies.
Overall, "catalysed" describes an event or reaction that was significantly influenced, accelerated, or facilitated by the presence or action of a catalyst.
The word "catalysed" is derived from the noun "catalyst", which comes from the Greek word "katalūsis", meaning "dissolution" or "decomposition". The term was first introduced in 1836 by the Swedish chemist Jöns Jacob Berzelius to describe substances that accelerate chemical reactions without being consumed in the process. Over time, the noun "catalyst" gave rise to the verb "catalyze", which means to facilitate or accelerate a reaction, resulting in the word "catalysed".
