In Freundlich adsorption isotherm

Question:

In Freundlich adsorption isotherm at moderate pressure, the extent of adsorption $\left(\frac{x}{m}\right)$ is directly proportional to $P^{x}$. The value of $x$ is

  1. Zero

  2. $\frac{1}{\mathrm{n}}$

  3. 1

  4. $\infty$


Correct Option: , 2

Solution:

As per Freundlich adsorption isotherm

$\left(\frac{x}{m}\right)=K P^{\frac{1}{n}} \rightarrow x=\frac{1}{n}$

Hence answer is (2)
