In chemical adsorption
WebTo be adsorbed, an adsorbate molecule must find its way to the adsorbent particle by convection, diffuse through the fluid film surrounding the particle, travel by diffusion along the length of a pore until it finds a vacant adsorption site, … Webof adsorption up to about 600 kJ/mole for C-N bonds and 800 kJ/mole for chemical bonds. A chemical bond involves sharing of electrons between the d- a garded as the formation of a surface compound. Due to the bond strength, chemical adsorption is difficult to reverse. Physical adsorption takes place on all surfaces
