Correct Answer – A
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.

Correct Answer – A
According to Freundlich adsorption isotherm, we have
`(x)/(m)=kP^(1//n)`
when `1//n` is `1` for low pressure region but `0` for high pressure region.
