    A plot of log \[\frac{x}{m}\] versus log p for adsorption of a gas on a solid gives a straight line with slope equal to m

    A)  \[\frac{1}{n}\]                         

    B)  log K

    C)  - log K             

    D)  n

    Correct Answer: A

    Solution :

    According to Freundlich adsorption isotherm\[\frac{x}{m}=k{{p}^{1/n}}\] Taking log on both sides \[\log  \frac{x}{m} =\,\,\frac{1}{n} log\,\,p +log\,\,K\] Compare with \[\operatorname{y} =mx + c\] So slope, \[m=\frac{1}{n}\] \[Slope\,\,=\,\,\,\frac{1}{n}\,\,x+C\]
