Langmuir Isotherm

Which of the following statements are correct with respect to adsorption of gases on a solid ? (i) The ectent of adsorption is equal to KP^(n) according to Freundlich isotherm. (ii) The extent of adsorption is equal to KP^(1//n) according to Frendlich isotherm. (iii) The extent of adsorption is equal to (1+bP)/aP according to Langmuir isotherm. (iv) The extent of adsorption is equal to aP/(1+bP) according to Langmuir isotherm. (v) Freundlich adsorption isotherm fails at low temperature.

Consider the following statement about Langmuir isotherm : (i) The free gas and adsorbed gas are in dynamic equilibrium (ii) All adsorption sites are equivalent (iii) The initially adsorbed layer can act as a substrate for further adsorption. (iv) The ability of a molecule to get adsorbed at a given site is independent of the occuption of neighbouring sites The correct statement are

Derive the following: a. Langmuir iostherm b. Freundlich iostherm

The variation of (p)/((x//m)) as a function of p when Langmuir's isotherm valid is :

An adsorption isotherm equation proposed by Langmuir is of the form V = (V_(0)bPO)/((1 + bP)) where V is the volume of gas adsorbed at pressure P. For a given adsorbate/adsorbent system, V_(0) and b are constants. The dependence of V on P can be depicted as
