Which of the following statements is incorrect regarding physissorptions ?        [AIEEE 2009]
  • a)
    More easily liquefiable gases are adsorbed readily
  • b)
    Under high pressure it results into multi molecular layer on adsorbent surface
  • c)
     Enthalpy of adsorption (ΔHadsorption) is low and positive
  • d)
     If occurs because of van der Waal's forces
Correct answer is 'C'. Can you explain this answer?
