Vedclass · Answer

(B) $1$. Adsorption is a surface phenomenon where the concentration of a substance increases at the surface of another substance. This is correct.$2$. In physical adsorption (physisorption),multi-molecular layers are formed due to weak van der Waals forces. This is correct.$3$. In adsorption,bonds (either physical or chemical) are formed between the adsorbent and the adsorbate. This is correct.$4$. The Freundlich adsorption isotherm is given by $x/m = kP^{1/n}$. At high pressure,$1/n$ approaches $0$,so $x/m = kP^0 = k$ (a constant). The statement $x/m = ap$ is incorrect as it implies a linear relationship at high pressure,which is not true.
