    The equation for Freundlich adsorption isotherm is

    A) \[\frac{x}{m}=k{{p}^{1/n}}\]                      

    B) \[x=mk{{p}^{1/n}}\]

    C) \[\frac{x}{m}=k{{p}^{-n}}\]                        

    D) all of these

    Correct Answer: D

    Solution :

    Freundlich adsorption isotherm \[\frac{x}{m}=k{{p}^{1/n}}\] Here, \[\frac{x}{m}=\]amount of gas adsorbed by adsorbent per gram k and n = constant p = pressure Other forms are \[x=mk{{p}^{1/n}}\] \[\frac{x}{m}=k{{p}^{-n}}\]
