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)

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

Answer 2

The empirical relation, $viz., \frac{x}{m}=kc^{1/n}$, put forward by Freundlich is known as Freundlich's adsorption isotherm. Taking log on both sides log$\left(\frac{x}{m}\right)= \log \,k+\frac{1}{n} \log \,c$
