Which among the following statements are NOT collects w.r.t. adsorptio...
Explanation:
Statement (a): The extent of adsorption is equal to KP^(1/n) according to the Freundlich isotherm.
This statement is a correct representation of the Freundlich isotherm equation. According to the Freundlich isotherm, the extent of adsorption (x/m) is directly proportional to the equilibrium pressure (P) raised to the power of 1/n, where n is a constant. Therefore, statement (a) is a collect statement.
Statement (b): Decrease of temperature and increase of pressure both tend to cause an increase in the magnitude of adsorption of a gas on solid.
This statement is also correct. According to the Le Chatelier's principle, a decrease in temperature and an increase in pressure both favor the exothermic process of gas adsorption on a solid. This leads to an increase in the magnitude of adsorption. Therefore, statement (b) is a collect statement.
Statement (c): The extent of adsorption is equal to (KP)^(1/3) / (KP)^(1/3) for a triatomic gas [A3(g)] undergoing dissociative adsorption.
This statement is a correct representation of the extent of adsorption for a triatomic gas undergoing dissociative adsorption. The extent of adsorption is proportional to (KP)^(1/3) / (KP)^(1/3), which simplifies to 1. Therefore, statement (c) is a collect statement.
Statement (d): Adsorption is always a physical phenomenon.
This statement is incorrect. Adsorption can be both a physical and chemical phenomenon. Physical adsorption, also known as physisorption, occurs due to weak van der Waals forces between the gas molecules and the solid surface. On the other hand, chemical adsorption, also known as chemisorption, involves the formation of chemical bonds between the gas molecules and the solid surface. Therefore, statement (d) is a NOT collect statement.
In conclusion, statement (d) is the correct answer as it does not accurately represent the adsorption of gases on a solid.
