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 .
