In Freundlich adsorption isotherm at moderate pressure,

Question:

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

  1. $\infty$

  2. 1

  3. Zero

  4. $\frac{1}{n}$


Correct Option: , 4

Solution:

$\frac{x}{m}=p^{x}$

the formula is $\frac{x}{m}=p^{1 / n}$

Hence $x=\frac{1}{n}$

The value of 'n' is any natural number.
