Characteristics of Catalysis
Various properties/characterstics of the catalyst are added below,
- At the end of the reaction, the mass and chemical makeup of a catalyst remains unchanged.
- The reaction cannot be started by the catalyst.
- In most cases, the catalyst is quite specific.
- The catalyst has no ability to alter the state of equilibrium.
- Changes in temperature affect the pace of catalytic reactions, just as they do in the absence of a catalyst.
Features of Solid Catalysis
Various features of the solid catalysis of any chemical reaction are,
Catalyst Activity
Catalyst activity refers to how quickly they may speed up chemical reactions. In some reactions, the rate of acceleration can reach 1010 times. In the presence of platinum as a catalyst, the reaction between H2 and O2 to generate H2O, for example, occurs with explosive violence. H2 and O2 can be held indefinitely without undergoing any reactions in the absence of a catalyst.
Catalyst Selectivity
It is possible for catalysts to direct reactions to produce certain products (excluding others).
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.
