In Freundlich adsorption isotherm, the value of 1/n is
(a) between 0 and 1 in all cases
(b) between 2 and 4 in all cases
(c) 1 in case of physical adsorption
(d) 1 in case of chemisorption
In Freunlich adsorption isotherm,
x/m = kp1/n
the value of n is always greater than 1. So, the value of 1/n lies between 0 and 1 in all cases.
