Which of the following statements is incorrect regarding physisorptions ?

Multiple Choice Options

  • A It occurs because of vander Waal’s forces.
  • B More easily liquefiable gases are adsorbed readily.
  • C Under high pressure it results into multi molecular layer on adsorbent surface.
  • D Enthalpy of adsorption ( ΔHadsorption\Delta H_{adsorption} ) is low and positive

Step-by-Step Verified Solution

In adsorption when two molecule comes closer then bond is created between the molecules and we know when bond is created between molecules the energy gets released so, Adsorption is an exothermic process, hence ΔH\Delta H will always be negative .
