In Freundlich adsorption isotherm, slope of AB line is :

Question:

 In Freundlich adsorption isotherm, slope of AB line is : 

  1. $\log n$ with $(n>1)$

  2. $\mathrm{n}$ with $(\mathrm{n}, 0.1$ to $0.5)$

  3. $\log \frac{1}{n}$ with $(n<1)$

  4. $\frac{1}{\mathrm{n}}$ with $\left(\frac{1}{\mathrm{n}}=0\right.$ to 1$)$


Correct Option: , 4

Solution:

$\frac{x}{m}=K(P)^{1 / n}$

$\log \left(\frac{x}{m}\right)=\log K+\frac{1}{n} \log P$

$y=c+m x$

$\mathrm{m}=1 / \mathrm{n}$ so slope will be equal to $1 / \mathrm{n}$.
