Question

For a linear plot of $log\left(x/m\right)$ versus $logP$ in a Freundlich adsorption isotherm, which of the following statements is correct? (k and n are constants)

• A. $\frac{1}{n}$ appears as the intercept
• B. Only $\frac{1}{n}$ appears as the slope
• C. log $\left(\frac{1}{n}\right)$ appears as the intercept
• D. Both $k$ and $\frac{1}{n}$ appear in the slope term

Answer 1

The correct option is B Only $\frac{1}{n}$ appears as the slope

According to Freundlich adsorption isotherm,
$\frac{x}{m}=k{P}^{\frac{1}{n}}$
$log\frac{x}{m}=logk+\frac{1}{n}logP$
