Question

The equation for Freundlich adsorption isotherm is

• A. $ \frac{x}{m}=kp^{1/n} $
• B. $ x=mkp^{1/n} $
• C. $ \frac{x}{m}=kp^{-n} $
• D. all of these

Answer 1

Answer: (D)

Freundlich adsorption isotherm
$ \frac{x}{m}=kp^{1/n} $
Here, $ \frac{x}{m}= $ amount of gas adsorbed by
adsorbent per gram
$k$ and $n =$ constant
$p =$ pressure
Other forms are $ x=mkp^{1/n} $
$ \frac{x}{m}=kp^{-n} $
