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.

Catalyst at work in the body?
Biological catalysts in organisms are called enzymes.
How does catalyst enable a reaction to happen more quickly?
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.
What is the catalyst for sodium persulfate?
Hydrogen peroxide will work.
Do catalyst work better in hot or cold water?
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.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.

How do quaternary ammonium compounds work?
it works as a catalyst
What is the catalyst for sodium persulfate?
Hydrogen peroxide will work.
Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.

Who invented the catalyst?
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.
What is the job of catalyst?
Catalysts work by lowering the "start-up" energy of a reaction.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
A substance that speeds up rate of a chemical reaction?
Catalyst, biocatalyst or enzyme.
Which does a catalyst not change?
Catalyst is not a reactant.
