The Correct Option is C
Solution and Explanation
At lower pressure, the graph is nearly straight and sloping, i.e.,
$\frac{x}{m} \propto p^1$
or $\frac{x}{m} =$ constant $\times p^1$
At high pressure, $\frac{x}{m}$ becomes independent of value of pressure.
$\frac{x}{m} \propto p^0$
or $\frac{x}{m} = $ constant
In the intermediate range of pressure, $\frac{x}{m} $ will depend on $p$ raised to powers between $1$ and $0$, i.e., fractions.
$\frac{x}{m} \propto p^{\frac{1}{n}}$
or $\frac{x}{m} =$ constant $\times p^{\frac{1}{n}}$
$\frac{x}{m} \propto p^1$
or $\frac{x}{m} =$ constant $\times p^1$
At high pressure, $\frac{x}{m}$ becomes independent of value of pressure.
$\frac{x}{m} \propto p^0$
or $\frac{x}{m} = $ constant
In the intermediate range of pressure, $\frac{x}{m} $ will depend on $p$ raised to powers between $1$ and $0$, i.e., fractions.
$\frac{x}{m} \propto p^{\frac{1}{n}}$
or $\frac{x}{m} =$ constant $\times p^{\frac{1}{n}}$

Applications of surface chemistry are:
Adsorption:
The process of attraction and aggregation of the molecules of a substance on the surface of a solid is known as adsorption. For Example, N2 adsorbs on the surface of activated charcoal
Two types of adsorption are:-
- Chemisorption: It is also known as Chemical Adsorption.
- Physisorption: It is also known as Physical Adsorption.
Corrosion:
The process through which the refined metals convert themselves into more stable compounds is known as corrosion.
Crystallisation:
The type of technique used in order to purify the substances to separate Solids from liquids is known as crystallisation.
Heterogeneous Catalysis:
The process wherein a catalyst is used in order to increase the rate of a chemical reaction is known as catalysis. The catalyst does not undergo any transformation and can be recovered in a chemically unchanged state.
There are two types of catalysis:-
- When the catalyst involved and the reacting substances are same states of matter or in the same phase, it is known as Homogeneous Catalysis.
- When the catalyst involved and the reacting substances are in different states of matter or different phases, it is known as Heterogeneous Catalysis.
