WebThe 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, , is related to the volume of it, V, adsorbed … WebMar 31, 2024 · The isotherm was derived by consideration of monolayer adsorption dynamically. At constant temperature T, the adsorbed volume of gas at standard condition V follows the equation shown below: V=\frac {\mathrm {Kp} {V}_m} {1+\mathrm {Kp}} (17.1) Here, K is a constant, p is an equilibrium pressure, and V m is saturated adsorption …
