MolSynapse / Question bank / Surface Chemistry / Adsorption: physisorption vs chemisorption, Freundlich and Langmuir isotherms

NEET levelSingle correct optionDifficulty 1 of 3sc006

In the Freundlich isotherm $x / m = k p^{1/ n}$ , the extent of adsorption becomes independent of pressure when $1/ n$ equals:

A $1$
B $0.5$
C $\infty$
D $0$

Answer: D

If

1/ n = 0

then

p^{0} = 1

and

x / m = k

, a constant. If

1/ n = 1

the adsorption is directly proportional to pressure.
