From Freundlich adsorption isotherm, if $ log \frac{x}{m} $ is plotted in $ y $ -axis and $ log\,p $ in $ x $ -axis, the slope will be
(Where $ 'k' $ and $ 'n' $ are constants that depend on the nature of the adsorbent and the gas at a particular temperature, $ 'x' $ is the mass of gas adsorbed on mass $ 'm' $ )
- $ n $
- $ \frac{1}{n} $
- $ log\,k $
- $ \frac{1}{log\,k} $
The Correct Option is B
Solution and Explanation
According to Freundlich adsorption isotherm :
$\frac{x}{m}=k\cdot p^{\frac{1}{n}}$
$log \frac{x}{m}=log\,k+\frac{1}{n}log\,p$

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.
