As we learned inc oncept 

Logarithmic graph of Freundlich isotherm -

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

- wherein

The slope of the straight line gives the value of 1/n. The intercept on y-axis gives the value of log K.

 

  

According to Treundlich adsorption, 

Isotherm, \frac{x}{m}= Kp^{\frac{1}{n}}

D \log \frac{x}{m}= \log K +\frac{1}{n}\ log p

Plotting the above equation in graph, we get

 

 

 

The slope gives the value of 1/x
