Question

The equation for Freundlich adsorption isotherm is:

• A. $\frac{x}{m}=k{p}^{1/n}$
• B. $x=mk{p}^{1/n}$
• C. $\frac{x}{m}=k{p}^{-n}$
• D. All of these

Answer 1

Answer: (D)

All of these

Freundlich adsorption isotherm given relationship between pressure and amount of substrate adsorbed.
$x/m=k{p}^{\frac{1}{n}}$ (where x/m = amount adsorbed p= pressure)
or $x=m\cdot k{p}^{\frac{1}{n}}$
or $x/m=k{p}^{-n}$
$\therefore$ All equations represent Freundlich adsorption isotherm.
