What is catalysis explain with examples?

Catalysis in chemistry:

Cataysis in chemistry is located below here it’s types reactions and biochemistry is discussed.First we have to know about catalysis:

Catalysis:

The term “catalysis” refers to a process that aims to modify the chemical kinetics by lowering the energy barrier to be crossed. The goal of catalysis is to increase the rate at which a chemical reaction occurs or sometimes to favor one reaction over another.

Types of catalysis in chemistry:

1.Homogeneous catalysis

2.Heterogeneous catalysis

 3.Enzymatic catalysis

1.Homogeneous catalysis :

Catalysis is described as “homogeneous” when the  reactants and the catalyst are in the same phase. This is often the case in organic chemistry , with reagents in solution.

2.Heterogeneous catalysis :

In heterogeneous catalysis, on the other hand, the reactants and the catalyst are in different phases. Generally, the catalyst is in solid form and the reagents in gaseous or liquid form .

3.Enzymatic catalysis :

So-called enzymatic catalysis is a kind of link between the two. It can be considered homogeneous at the macroscopic level but, at the molecular level, the catalysis reactions are on the surface of the enzymes , as in the case of heterogeneous catalysis.

Industrial catalysis:

Many industrial processes become more cost effective through catalytic processes. Catalysis allows for better yields, fewer steps in a process, and saves time and energy .

In the field of chemical synthesis , that of ammonia (NH 3 ), made from hydrogen (H 2 ) and nitrogen (N 2 ), is a good example. This reaction benefits from iron catalysis . Catalysis is also used for petroleum refining or the reduction of nitrogen oxides in catalytic converters .

Catalytic Reactions:

Catalysis in Biochemistry

The majority of biological reactions are catalytic reactions. Catalysis is, in this case, carried out by enzymes that accelerate biochemical processes such as digestive metabolism , reproduction, transcription of genetic information , etc.
