Mechanism of Catalysis
We know that a catalyst decreases the activation energy of the reaction and increases the rate of the reaction. The mechanism of the catalysis is defined by a five-step process that is added below,
Step 1: Firstly reactant molecule is diffused on the catalytic surface.
Step 2: Now the reactant molecules get adsorped on the catalytic surface.
Step 3: Then the intermediate molecules are formed on the catalytic surface.
Step 4: Then desorption of the product molecule do formed by the catalytic surface.
Step 5: Now at last the diffusion of product molecules from the catalytic surface to form Final product.
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.
