The homogeneous catalyst is one that is formed by a homogeneous mixture with the reactants, this process is very different from the heterogeneous catalyst because it is easier to separate, it is much firmer and its degradation is slower than a heterogeneous catalyst, where the homogeneous catalyst is one of the different phases to the reactants that are those that combine with one of the reactants, creating an intermediate compound that reacts with the other easier. This catalyst does not influence the equilibrium of the reaction, because the putrefaction of the reaction products is precipitated to a similar degree.
For example, the homogeneous catalyst is nitric oxide in the catalysis of sulfur trioxide formation by reacting sulfur dioxide with oxygen, both at the beginning and at the end of the reaction where there is a certain amount of nitric oxygen.
This catalyst makes a homogeneous mixture with the reactants, but not only does it do nothing else in the same state of union as water and oil have the same state but do not form homogeneous mixtures, the homogeneous catalyst is one of the most common within These catalysts and the most used is the H + acids, but it is the least useful for the industry.
The heterogeneous catalyst does not increase the speed of a reaction, it only leads to the reactants by another reaction with less energy of increasing the intensity of speed that results in the same product as the reaction without catalyst, in addition there are various types of homogeneous catalyst such as Metal oxides, organometallic compounds, acids, bases and the classics in biological systems, enzymes.
