    In Freundlich adsorption isotherm, the value of \[1/n\] is

    A)  1 in case of physical adsorption

    B)  1 in case of chemisorption

    C)  between 0 and 1 in all cases

    D)  between 2 and 4 in all cases

    Correct Answer: C

    Solution :

     Freundlich adsorption isotherm is \[\frac{X}{m}=K{{P}^{1/n}}\] If \[P\to 0,\,n=1\]\[\therefore \]\[\frac{X}{m}=KP\] If P is high; \[n=0\]\[\therefore \]\[\frac{X}{m}=K{{P}^{0}}\]
