In frenudlich adsorption isotherm, the value of `1//n` is

Options

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

Answer

A

Explanation

In Freundlich adsorption isotherm,
`(x)/(m)= kp^(1//n)`
Where, x = amount of adsorbent
m = amount of adsorbate
The value of n is always greater than 1. So, the value of 1/n lies between 0 and 1 in all cases.
