Question

Which of the following graphs represents the Freundlich adsorption isotherm correctly?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

The Freundlich adsorption isotherm is mathematically expressed as:
$\frac{x}{m}=K{P}^{1/n}$
or, $log\frac{x}{m}=logK+\frac{1}{n}logP$

On comparing the above equation with the equation of a straight line, $y=mx+c$

We get,
$y=log\frac{x}{m}$
$x=logP$
$m=\frac{1}{n}$
$c=logK$

which is option $\left(b\right)$
