Question

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

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

Answer 1

Answer: (A)

Freundlich's adsorption isotherm is given as:
$\frac{x}{m}=k{p}^{\frac{1}{n}}$
When $x=1,\frac{x}{m}=kp$ (at low pressure)
When $n>1,\frac{x}{m}=k$ (at high pressure)
