For adsorption of gas in solid \[\log \left( \frac{x}{m} \right)\] versus log 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 \[\log \frac{x}{m}=\log K+\frac{1}{n}\log P\] Plat 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.
