Question

For Freundlich isotherm a graph of log $\frac {x}{m}$ is plotted against $log\, P$. The slope of the line and its y-axis intercept, respectively corresponds to

• A. $\log \frac{1}{n},k$
• B. $\log \frac{1}{n},\log k$
• C. $\frac {1}{n}, k$
• D. $\frac{1}{n}, \log k$

Answer 1

Answer: (D)

$\frac{1}{n}, \log k$

Answer 2

According to Freundlich adsorption isotherm

$\frac{x}{m}=k p^{1 / n}$

Taking log both side

$\log \frac{x}{m}=\frac{1}{n} \log p+\log k$

Graph between $\log \frac{x}{-}$ against $\log p$
