Physisorption is defined as adsorption in which force between adsorbate and adsorbent is physical van der Waals force also known as London force.
What kind of forces exists between adsorbate and adsorbent in chemical adsorption?
Iodine molecules are held in the crystals lattice by ..............
(a) London forces (b) dipole-dipole interacions
(c) Covalent bonds (d) coulombic forces
Ionic bond involves the electrostatic force of attraction between the positive and negative ions which is stronger than the force of attraction between atoms in a covalent bond.
