Information About

Physisorption




  • Low temperature, always under the Critical Temperature of the adsorbate;

  • Type of interaction: Intermolecular forces ( Van Der Waals Forces );

  • Low Enthalpy : ΔH < 20 KJ/mol;

  • Adsorption takes place in multilayers;

  • Low activation energy.

  • The energy state of adsorbate is not altered.

  • Reversible.
