Question

Correct equation of Freundlich isotherm is

• A. $\log \left(\frac{m}{x}\right)=\log k+\frac{1}{n}\log c$
• B. $\log \left(\frac{x}{m}\right)=\log c+\frac{1}{n}\log k$
• C. $\log \left(\frac{x}{m}\right)=\log c+\frac{1}{k}\log c$
• D. $\log \left(\frac{x}{m}\right)=\log k+\frac{1}{k}\log c$

Answer 1

Answer: (A)

The empirical relation,

$viz.,\frac{x}{m}=k{c}^{1/n}$,

put forward by Freundlich is known as Freundlich's adsorption isotherm.

Taking log on both sides

log$\left(\frac{x}{m}\right)=\log k+\frac{1}{n}\log c$
