What are postulates of Langmuir adsorption isotherm?

1) The layer of the adsorbed gas is only one molecule thick means it is a unimolecular layer in nature.
2) Adsorption involves two opposite processes which mean condensation of gas molecules and evaporation of these molecules.
3) The rate of condensation of a gas is proportional to the unoccupied surface of the adsorbent while that of evaporation to its covered surface.
