A catalyst speeds up the rate of a chemical reaction.
A catalyst speeds up chemical reactions without suffering chemical change itself. It basically increases the amount of collisions made in a reaction, therefore speeding it up (as collisions and their force depict the speed of the reaction), however, it is not used up in the reaction, making it reusable, especially in industrial processes
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
A catalyst speeds up a chemical reaction without being a part of the reaction. The catalyst does not undergo any chemical change during the reaction, but it decreases the amount of activation energy needed to start the reaction.
A catalyst provides an alternate reaction path-way that requires less activation energy.
They speed them up
Catalysts are used to speed up reactions
The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
The role of a catalyst is to quicken the chemical reaction . On reacting, it subsequently appears as a product in the next step of the reaction.
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.

The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Adding a catalyst a chemical reaction can occur with a lower activation energy.
A catalyst doesn't undergo a chemical change during a chemical reaction.

* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
