What does catalysis mean?
The term “catalysis” refers to a process that aims to modify theby lowering the energy barrier to be crossed. The goal of catalysis is to increase the at which a occurs or sometimes to favor one reaction over another.
Types of catalysis :
Homogeneous catalysis, heterogeneous catalysis and enzymatic catalysis
Homogeneous catalysis :
Catalysis is described as “homogeneous” when theand the are in the same phase. This is often the case in organic , with reagents in solution.
Heterogeneous catalysis :
In heterogeneous catalysis, on the other hand, the reactants and the catalyst are in different phases. Generally, the catalyst is inform and the reagents in gaseous or .
Enzymatic catalysis :
So-calledcatalysis 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 , as in the case of heterogeneous 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.
In the field of, that of (NH 3 ), made from (H 2 ) and (N 2 ), is a good example. This reaction benefits from catalysis . Catalysis is also used for or the reduction of in .
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, reproduction, of information , etc.
