Limitations of Freundlich Isotherm Freundlich isotherm only approximately explains the behaviour of adsorption. The value of 1/n can be between 0 and 1, therefore the equation holds good only over a limited range of pressure. When 1/n = 0, x/m is constant, the adsorption is independent of pressure. piscataway marriage licenseWebb4 feb. 2024 · The key difference between Freundlich and Langmuir adsorption isotherms is that Freundlich adsorption isotherm is empirical, whereas Langmuir adsorption isotherm is theoretical.
