Adsorption of Gas on the Surface of Solid
Introduction:
Adsorption is a process in which a gas or liquid adheres to the surface of a solid or liquid. In this process, the molecules of the gas or liquid become attached to the surface of the solid or liquid. There are two types of adsorption: physical adsorption (physisorption) and chemical adsorption (chemisorption).
Correct Statement:
Option 'A' is not correct regarding the adsorption of a gas on the surface of solid. On increasing pressure, adsorption does not always keep on increasing. This is because the adsorption is dependent on the nature of the gas and the solid surface. There is a limit to the amount of gas that can be adsorbed on the surface of a solid. Beyond this limit, the adsorption becomes saturated and does not increase further with an increase in pressure.
Enthalpy and Entropy Changes:
The process of adsorption is accompanied by a change in enthalpy and entropy. The enthalpy change is negative, indicating that the process is exothermic. The entropy change is also negative, indicating that the molecules become more ordered as they are adsorbed on the surface.
Chemisorption and Physisorption:
Chemisorption is a specific type of adsorption in which the gas molecules are chemically bonded to the surface of the solid. This type of adsorption is more specific than physisorption, in which the gas molecules are only weakly attracted to the surface of the solid.
Reversibility:
Adsorption is a reversible process. The adsorbed molecules can be desorbed from the surface of the solid by changing the conditions such as temperature, pressure, or concentration. The extent to which the adsorption is reversible depends on the nature of the adsorbate and the adsorbent.
Conclusion:
In conclusion, the statement that is not correct regarding the adsorption of a gas on the surface of solid is option 'A'. On increasing pressure, adsorption does not always keep on increasing. The other statements are correct, including the negative enthalpy and entropy changes, the specificity of chemisorption, and the reversibility of the process.
