What is Catalysis in Chemistry?

Catalysis is a process that can speed up and slow down a chemical reaction. The substance which cause the change in rate of recation without being consumed at the end of the reaction.

Catalysis in chemistry is a process that increase or decrease the rate of a chemical reaction caused by the inclusion of a catalyst, which is not consumed in the chemical reaction and is used multiple times.Every chemical reaction proceeds after overtaking a certain energy and this energy is called the Activation Energy of the reaction. The catalyst alters the Activation Energy of the chemical reaction and increases and decreases the rate of the reaction.

Catalysis Definition

Catalysis is the generally defined as the process that increases the rate of the reaction and makes the chemical reaction faster.

Catalysis Example

The example of Catalysis is mentioned in the following reactions:

Catalysis – Definition, Mechanism, Types, Characteristics

Catalysis in Chemistry is defined as the process in which the rate of the reaction is influenced by the presence of some specific substance. These specific substances are called Catalysts. The catalyst is never consumed during the chemical reaction.

A catalyst changes the activation energy of the reaction, i.e. the energy required for occurring the reaction. and thus alters its rate. In general, a catalyst lowers the activation energy of the chemical reaction and this process is called the Catalysis.
