If adsorption of a gas on a solid is limited to monolayer formation , then which of the following statement are true ? At low pressures x/m varies proportionately with P, At moderate pressures, x/m varies less than proportionately with P, At high pressure , x/m becomes independent of P, at high pressure , x/m varies more than proportionately with P.

Which of the following relation is/ are correct for Langmuir adsorption isotherm? (i) x/m = constant (at high pressure) (ii) x/m = constant x p^(1//n) (at intermediate pressure) (iii) x/m = constant x p^n (at lower pressure)

A group between x/m and the presure P of the gas at a constant temperature is called adsorption siotherm. Where x is the no. of moles of the adsorbate and m is the mass of the adsorbent. adsoption isotherms of different shaopes have been experimentally observed .. According to frundlich adosroption isthem, x//m = KP^(1//n) where K and N are constant paraments depending upon the nature of the solid and gas Inn the given isotherm select the incorrect statement : x/m proptoP^(1//n along OA, x/m proptoP^(1//n when point B is reached , x/m does not increase as rapidly with pressure along BC due to less surface area availble for adsorption .

A group between x/m and the presure P of the gas at a constant temperature is called adsorption siotherm. Where x is the no. of moles of the adsorbate and m is the mass of the adsorbent. adsoption isotherms of different shaopes have been experimentally observed .. According to frundlich adosroption isthem, x//m = KP^(1//n) where K and N are constant paraments depending upon the nature of the solid and gas graph between log (x/m) and log P is a straight line a t angle 45^(@) with intercept OA as shown . hence, (x/m) at a pressure of 2 atm is :
