Question

In Freundlich Adsorption isotherm, the value of $1/n$ is :

• A. $1$ in case of physical adsorption
• B. $1$ in case of chemisorption
• C. between $0$ and $1$ in all cases
• D. between $2$ and $4$ in all cases

Answer 1

Answer: (C)

between $0$ and $1$ in all cases

Answer 2

In Freundlich adsorption isotherm,
$\frac{x}{m} = k p^{1/n}$ the value of $n$ is always greater than $1$.
So, the value of $1/n$ lies between $0$ and $1$ in all cases.
