Question

what is Adsorption Isotherm??

Answer 1

Answer:

Explanation:

Freundlich adsorption isotherm is obeyed by the adsorption where the adsorbate forms a monomolecular layer on the surface of the adsorbent.

\frac{x}{m}=K.{{p}^{\frac{1}{n}}};\,\,\log \frac{x}{m}=\frac{1}{n}\log p+\log k  

x represents the amount of gas adsorbed on the m gram of adsorbent, K and n are adsorption constants, ‘p’ is pressure n always greater than one.  

A major drawback of Freundlich adsorption isotherm it fails at high pressure. It could not explain the multi-layered adsorption process.

Answer 2

Answer:

curve obtained by plotting at constant temperature the quantity of adsorbate against the concentration of the substance in the original gas or solution.
