Physisorption, also called physical adsorption,'s a process in which the electronic structure of the atom or molecule's barely perturbed upon adsorption. The weak bonding of physisorption's due to the induced dipole moment of a nonpolar adsorbate interacting with its own image charge in the polarizable solid. Introduction The fundamental interacting force of physisorption's caused by van der Waals force. Even though the interaction energy's very weak (~10–100 meV), physisorption plays an i… (More on Physisorption)
