Question

What will be the Freundlich's adsorption isotherm equation at high pressure?

• A. $\frac{\text{x}}{\text{m}}=\text{k}$
• B. $\frac{\text{x}}{\text{m}}=\text{k}\text{p}$
• C. None of these
• D. $\frac{\text{x}}{\text{m}}\text{=}\frac{\text{k}}{\text{p}}$

Answer 1

Answer: (A)

Freundlich's adsorption isotherm is given as:

$\frac{\text{x}}{\text{m}}{\text{=Kp}}^{\frac{1}{n}}$

$\text{W}\text{h}\text{e}\text{n}\text{x}=1,\frac{\text{x}}{\text{m}}=\text{k}\text{p}\left(\text{a}\text{t}\text{l}\text{o}\text{w}\text{p}\text{r}\text{e}\text{s}\text{s}\text{u}\text{r}\text{e}\right)$

$\text{W}\text{h}\text{e}\text{n}\text{n}>1,\frac{\text{x}}{\text{m}}=\text{k }\left(\text{a}\text{t}\text{h}\text{i}\text{g}\text{h}\text{p}\text{r}\text{e}\text{s}\text{s}\text{u}\text{r}\text{e}\right)$
