A catalyst is a substance that helps to increase the rate of a chemical reaction without being consumed itself in the reaction. In other words a catalyst provides a new reaction pathway with a loweractivation energy than the original reaction pathway.
The net result is that catalysts speed up reactions by lowering the amount of energy needed to get the reaction going.
Catalysts can be either man-made or naturally occurring. Common examples of man-made catalysts include enzymes which are proteins that catalyze biochemical reactions in the body and catalytic converters which are used to reduce emissions from automobiles.
In general catalysts work by providing an alternative reaction pathway with a lower activation energy than the original reaction.
In the case of enzymes catalysts work by binding to the reactants of a reaction which brings them into closer proximity and thus lowers the activation energy needed for the reaction to occur.
Catalytic converters work by using a catalyst to convert harmful emissions from automobiles into less harmful emissions.
There are many different types of catalysts and they can be used to speed up a wide variety of reactions.

One of the most important things to remember about catalysts is that they are not consumed in the reactions that they catalyze. This means that they can be used over and over again to speed up the same reaction.
If you have any questions about catalysts or how they work be sure to ask your teacher or another expert.
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction.
How do catalysts work?
Catalysts work by reducing the activation energy of the reaction which is the energy required to overcome the forces that keep the reactant molecules from coming together.
What is the activation energy of a reaction?
The activation energy of a reaction is the energy required to overcome the forces that keep the reactant molecules from coming together.
How do catalysts reduce the activation energy of a reaction?
Catalysts work by reducing the activation energy of the reaction which is the energy required to overcome the forces that keep the reactant molecules from coming together.
What are the benefits of using a catalyst?
The benefits of using a catalyst include increasing the rate of the reaction and reducing the amount of energy required for the reaction.
What are some examples of catalysts?
Some examples of catalysts include enzymes which are proteins that catalyze chemical reactions in the body and catalytic converters which are used to reduce emissions from automobiles.
How do enzymes work?
Enzymes work by catalyzing chemical reactions in the body.
What are catalytic converters?
Catalytic converters are devices that are used to reduce emissions from automobiles.
What are the types of reactions that catalysts can be used for?
Catalysts can be used for various types of reactions such as reduction oxidation and hydrolysis.
What is reduction?
Reduction is a type of reaction in which one molecule of a substance is reduced by another molecule.
What is oxidation?
Oxidation is a type of reaction in which a molecule of a substance is oxidized by another molecule.
What is hydrolysis?
Hydrolysis is a type of reaction in which a molecule of a substance is broken down by water.
What are some examples of reactions that catalysts can be used for?
Some examples of reactions that catalysts can be used for include reduction oxidation and hydrolysis.
What are the benefits of using a catalyst?
The benefits of using a catalyst include increasing the rate of the reaction and reducing the amount of energy required for the reaction.
What are some disadvantages of using a catalyst?
Some disadvantages of using a catalyst include the potential for the catalyst to poison the reactants and the need for the catalyst to be present in order for the reaction to occur.
