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

Options

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

C

Explanation

Freundlich adsorption isotherm is `X/m = KP^(1//n)`
If `P rarr 0, n=1 :. (X)/(m) = KP`
if `P` is high , `n=0 :. (X)/(m) = KP^(0)`.
