Question

Wired Faculty App

In reference to Freundlich adsorption isotherm, write the expression for adsorption of gases on solids in the form of an equation.

Solution

Freundlich adsorption isotherm for adsorption of gases on solids:

$straight x over straight m space equals space straight K subscript straight p superscript 1 over straight n end superscript It space can space also space be space written space as comma log straight x over straight m equals log space straight K space plus 1 over straight n log space straight p$

where, x is the mass of the adsorbate, m is the mass of the absorbent and p is the pressure of the gas and n is a constant which is greater than 1.
