Adsorption Theory of Catalysis:
The adsorption theory of catalysis explains that the rate of a reaction increases in the presence of a catalyst due to the process of adsorption. Catalysts are substances that speed up a chemical reaction without being consumed in the process.
The Role of Adsorption:
Adsorption refers to the process in which molecules of reactants are attracted and bind to the surface of the catalyst. The reactant molecules are held at the active sites of the catalyst, forming weak chemical bonds. This adsorption process occurs due to the presence of active centers or sites on the surface of the catalyst.
Increased Concentration of Reactants:
One of the key reasons why the rate of reaction increases with the use of a catalyst is because the concentration of reactants at the active centers becomes high due to adsorption. This increased concentration facilitates more frequent collisions between the reactant molecules, leading to an increase in the rate of reaction.
Increased Frequency of Collisions:
When the reactant molecules are adsorbed onto the surface of the catalyst, they come into close proximity with each other. This proximity increases the chances of successful collisions between the reactant molecules, which are necessary for the reaction to occur. As a result, the frequency of collisions between the reactant molecules increases, leading to an increase in the rate of reaction.
Lower Activation Energy:
Another important aspect of adsorption theory is that it lowers the activation energy of the reaction. Activation energy is the minimum energy required for a reaction to occur. The presence of a catalyst provides an alternative reaction pathway with a lower activation energy. When the reactant molecules are adsorbed on the catalyst surface, the energy barrier for the reaction is reduced, allowing the reaction to occur at lower temperatures or with less energy input. This lower activation energy further enhances the rate of reaction.
Conclusion:
In summary, the rate of reaction increases with the use of a catalyst due to the adsorption of reactant molecules onto the surface of the catalyst. This process leads to an increased concentration of reactants at the active centers, higher frequency of collisions between reactant molecules, and a lower activation energy. These factors collectively contribute to the overall acceleration of the reaction rate.
