                                        A plot of \[\log \,m/x\] versus \[\log \,\,p\] for the adsorption of a gas on a solid gives a straight line with slope equal to:

A)                                                                                                                                                                                             - log k  

B)                  n                           

C)                  \[\frac{1}{n}\] 

D)                  log k

Correct Answer: C

Solution :

                          The empirical relation \[\frac{x}{m}=k\,{{p}^{\frac{1}{n}}},\]put forward by Freundlich is known as Freundlich adsorption isotherm. Taking logarithm                 \[\log \frac{x}{m}=\log \,k+\frac{1}{n}\,\log \,\,p\]                 If a following curve is plotted
