Which of the following statements is incorrect regarding physisorption?

A

It occurs because of van der Walls' forces

B

More easily liquefiable gases are adsorbed readily

C

Under high pressure, it results in multi moleculer layer on adsorbent surface

D

Enthalpy of adsorption is low and positive.
