Question

Which one of the following gives a straight line for Freundlich adsorption isotherm?

• A. $\log \frac{x}{m}vs\log P$
• B. $\frac{x}{m}vs\frac{1}{P}$
• C. $\log \frac{x}{m}vs\log \frac{1}{P}$
• D. $\frac{1}{x}vsP$
  

Answer 1

The correct option is A $\log \frac{x}{m}vs\log P$

$\log \frac{x}{m}vs\log P$ gives a straight line for Freundlich adsorption isotherm.

$\log \frac{x}{m}=\frac{1}{n}\log P+logk$

Here, $\frac{1}{n}=$ slope of the line

$logk=$ intercept
