Which of the following statements is not correct for chemisorption and...
Introduction:
Chemisorption and physisorption are two types of adsorption processes that occur on the surface of a solid. While they both involve the adhesion of molecules to a solid surface, there are certain differences between them. Let's analyze the given statements to determine which one is not correct.
Statement Analysis:
a) Physical adsorption occurs at a low temperature and chemisorption occurs at all temperatures:
- This statement is correct. Physical adsorption, or physisorption, occurs at relatively low temperatures and is generally a reversible process. On the other hand, chemisorption can occur at all temperatures and involves chemical bonding between the adsorbate and the solid surface.
b) Magnitude of chemisorption decreases with rise in temperature while physisorption increases with rise in temperature:
- This statement is not correct. The magnitudes of both chemisorption and physisorption generally decrease with an increase in temperature. However, the decrease in magnitude is more significant in physisorption, while chemisorption is relatively less affected by temperature.
c) Chemisorption is irreversible and physisorption is reversible:
- This statement is correct. Chemisorption is a chemical process that involves the formation of strong chemical bonds between the adsorbate and the solid surface. These bonds are difficult to break, making chemisorption irreversible. On the other hand, physisorption is a physical process where weak van der Waals forces are involved. These forces can easily be overcome, allowing physisorption to be reversible.
d) In physisorption activation energy is low while in chemisorption it is high:
- This statement is correct. In physisorption, the activation energy required for adsorption is relatively low because weak van der Waals forces are involved. These forces do not require a significant amount of energy to overcome. In chemisorption, however, the activation energy is high because it involves the breaking and formation of strong chemical bonds.
Conclusion:
Based on the analysis, it can be concluded that option B is the correct answer as it does not accurately describe the temperature dependence of chemisorption and physisorption. The correct statement is that both chemisorption and physisorption decrease in magnitude with an increase in temperature, but the decrease is more significant in physisorption.
