A catalyst actually decreases the activation energy of a reaction in 2 ways:

1) By a process called adsorption, it attracts the molecules of the reactants to its surface so that they are closer together and can react more easily by colliding more successfully.

2) It creates a transition state, which is an inter mediate state before the final reaction occurs, which creates an intermediate, unstable compound using the catalyst itself. By the time the final product is formed, a new product as well as the original catalysy are remaining and the activation energy is considerably reduced.

Enzymes are a catalyst that is at work in the body. A catalyst will lower the amount of energy that is needed for a chemical reaction to occur.


The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.




Catalyst work in non living things while enzyme work inside living things. They are not catalyst but instead they can be called biocatalysts. Hope it helps.


No, a given catalyst will only catalyze certain types of reactions. Depending on the catalyst, it may be extremely specific, or it may catalyze a variety of similar reactions.


yes..it can work alone but also can work faster if catalyst also join it..


A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.


a catalyst speeds up chemical reactions



Because each catalyst has different particles in it that don't react with different atoms. Like dogs....


A catalyst is anything that speeds a chemical reaction but remains unchanged at the end of the reaction. They work by lowering the activation energy of the reaction.


Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.


An enzyme is a protein that acts as a catalyst in a living thingEnzymes are proteins which work as a biological catalyst, i.e. increases the rate of the chemical reaction.


The person that is credited with inventing the catalyst is Rayan Jafar. He created this catalyst in 1973 by having tomato sauce poured on some seeds and having them work better than they used to. He repeated this process several times.


Catalysts work by lowering the "start-up" energy of a reaction.


Positive Catalyst is a catalyst which increases the rate of reaction. In a wider sense, the term catalyst is used for positive catalyst.


POSITIVE CATALYST: The substance that increase the speed of reaction is called positive catalyst or catalyst. NEGATIVE CATALYST: The substance that reduces the speed of reaction is called negative catalyst or inhibitor.


In chemistry, they can work by adsorption (although there are other methods). This is when the catalyst attaches itself to the reactant particles and then weakens the bond between them, making it easier to react, thus 'lowering the activation energy' (the energy required for a reaction to start).


Saliva itself is not a catalyst but its contains the enzyme amylase, which is a catalyst.


Catalyst is not a reactant.


As far as I'm aware, the work "catalyst" only applies to things which work on enzymes. Baking powder is a mixture of an acid and an alkali, which reacts upon adding a liquid by releasing Co2. (Although some also react upon heating). It is a chemical reaction, not an enzymatic one, therefore I don't think you can consider it to be a catalyst.


what is the purpose of catalyst in textile paint?


No the catalyst is not consumed in the reaction, this is part of the definition of a catalyst.


Enzymes are also catalyst i.e they are biochmical catalyst.
