It also written as
x = mass of adsorbate
m = mass of adsorbent
p = equilibrium pressure of the gaseous adsorbate in case of experiments made in gas phase (gas/ solid interaction with gaseous species/adsorbed species).
C = equilibrium constant of adsorbate in case of experiments made with an aqueous solution in contact with dispersed solid phase (dissolved species/adsorbed species).
k and n are constants of a given adsorbate and adsorbent at a given temperature (from there, the item isotherm needed to avoid significant gas pressure fluctuations due to uncontrolled temperature variations in the case of adsorption experiments of a gas onto a solid phase).

Directions: In the following questions, A statement of Assertion (A) ...
Assertion (A): Extent of adsorption of adsorbate from solution phase increases with increase in amount of adsorbate in solution.
Reason (R): Freundlich’s equation describes the behaviour of adsorption from a solution.
The correct answer is option 'A' - Both A and R are true and R is the correct explanation of A.
Explanation:
Adsorption:
Adsorption is a process in which molecules or ions from a substance (adsorbate) are attracted and adhere to the surface of another substance (adsorbent). It is a surface phenomenon and can occur in various forms such as gas-solid adsorption, liquid-solid adsorption, and solution-phase adsorption.
Extent of Adsorption and Amount of Adsorbate:
The extent of adsorption refers to the amount of adsorbate molecules that are adsorbed onto the adsorbent surface. According to the statement of Assertion (A), the extent of adsorption increases with an increase in the amount of adsorbate in the solution. This means that as the concentration of the adsorbate in the solution increases, more adsorbate molecules will be available for adsorption onto the surface of the adsorbent. As a result, the extent of adsorption will increase.
Freundlich’s Equation:
Freundlich’s equation is an empirical equation that describes the behavior of adsorption from a solution. It is given as:
x/m = kC^n
Where:
x/m is the amount of adsorbate adsorbed per unit mass of adsorbent
C is the concentration of the adsorbate in the solution
k and n are constants that depend on the nature of the adsorbate and adsorbent
Explanation of Reason (R):
The reason stated in Reason (R) is that Freundlich’s equation describes the behavior of adsorption from a solution. This statement is correct. Freundlich’s equation is widely used to describe the adsorption behavior of various adsorbate-adsorbent systems in solution-phase adsorption. It provides a mathematical representation of the relationship between the amount of adsorbate adsorbed and the concentration of the adsorbate in the solution.
Conclusion:
Both Assertion (A) and Reason (R) are true. The increase in the extent of adsorption with an increase in the amount of adsorbate in the solution is supported by Freundlich’s equation, which describes the behavior of adsorption from a solution. Hence, option 'A' is the correct answer.
Reason (R): Freundlich’s equation describes the behaviour of adsorption from a solution.
The correct answer is option 'A' - Both A and R are true and R is the correct explanation of A.
