Freundlich adsorption isotherm is obeyed by the adsorption where the adsorbate forms a multimolecular layer on the surface of adsorbent .In such cases, the degree of adsorption varies linearly with pressure but at high pressure, it becomes independent of pressure
The relation of Freundlich adsorption isotherm is :
`(x)/(m)=kP^(1//n)`
where ,K and n are constants.
Langmuir adsorption isotherm is obeyed by the adsorption where the adsorbate forms only a unimolecular adsorbed layer. The mathematical relation of Langmuir isotherm is :
`(x)/(m) = (aP)/(1+bP)`
When `"log"((x)/(m))` is plotted against log P, we get a straight line with slope (1/n).
(a) True (b) False
