For adsorption of gas in solid,\[\log \left( \frac{x}{m} \right)\]versus \[log\text{ }P\]is linear with the slope equal to:

A)  \[K\]                                    

B)  \[log\,K\]

C)  \[n\]                                    

D)  \[\frac{1}{n}\]

Correct Answer: D

Solution :

                 Freundlich adsorption isotherm equation is: \[\log \frac{x}{m}=\log K+\frac{1}{n}\log \,P\] \[Plot\,of\,\log \left( \frac{x}{m} \right)\]and \[\log P\]is a  Straight line. The slope of the line is equal to \[\frac{1}{n}\]and intercept is equal to log K.
