Q. Correct equation of Freundlich isotherm is
AIIMS
AIIMS 2001
Surface Chemistry
A
$\log \left(\frac{m}{x}\right)=\log k+\frac{1}{n} \log c$
60%
B
$\log \left(\frac{x}{m}\right)=\log c+\frac{1}{n} \log k$
21%
C
$\log \left(\frac{x}{m}\right)=\log c+\frac{1}{k} \log c$
7%
D
$\log \left(\frac{x}{m}\right)=\log k+\frac{1}{k} \log c$
11%
Solution:
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$\left(\frac{x}{m}\right)= \log \,k+\frac{1}{n} \log \,c$
