The adsorption sites (heavy dots) are equivalent and can have unit occupancy. Also, the adsorbates are immobile on the surface.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes. This model even explains the effect of pressure i.e at these conditions the adsorbate’s partial pressure, pA{displaystyle p_{A}}, is related to the volume of it, V, adsorbed onto a solid adsorbent. The adsorbent, as indicated in the figure, is assumed to be an ideal solid surface composed of a series of distinct sites capable of binding the adsorbate.  The adsorbate binding is treated as a chemical reaction between the adsorbate gaseous molecule        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Ag{displaystyle A_{text{g}}} and an empty sorption site, S.
