Vedclass · Answer

(C) The Freundlich adsorption isotherm is the mathematical representation for the variation of the extent of adsorption $(x/m)$ with pressure $(p)$ at a given temperature. $x/m = k \cdot p^{1/n}$ where $n > 1$. Here,'$x$' is the mass of the gas adsorbed on mass '$m$' of the adsorbent at pressure '$p$'. '$k$' and '$n$' are constants that depend on the nature of the adsorbent and the gas at a particular temperature. Experimentally,it was determined that the extent of gas adsorption varies with pressure raised to the power $1/n$ until saturation pressure $p_s$ is reached. At high pressure,the value of $x/m$ becomes independent of pressure,meaning the equation $x/m = k \cdot p^{1/n}$ no longer holds as $1/n$ approaches $0$. Thus,the Freundlich adsorption isotherm fails at high pressure.
