Question

Which among the following statement is correct with respect to adsorption of gases on a solid? \I. The extent of adsorption is equal to $\mathrm{kp}^{	ext {n }}$ according to Freundlich isotherm \ II. The extent of adsorption is equal to $\mathrm{kp}^{1 / n}$ according to Freundlich isotherm \ III. The extent of adsorption is equal to $\frac{1+b p}{a p}$ according to Langmuir isotherm \ IV. The extent of adsorption is equal to $\frac{b p}{1+b p}$ according to Langmuir isotherm

Professor PC Thomas Classes · Answer

Langmuir isotherm at constant T relates extent of adsorption to $\frac{bp}{1+bp}$. Freundlich is $kp^{1/n}$.
