    Unit of equivalent conductance is:

    A)  \[oh{{m}^{-1}}\,c{{m}^{2}}\,{{(g-eq)}^{-1}}\]

    B) \[ohm\,cm\,(g-eq)\]

    C) \[ohm\,c{{m}^{2}}\,{{(g-eq)}^{-1}}\]

    D) \[oh{{m}^{-1}}\,cm\,{{(g-eq)}^{-1}}\]

    Correct Answer: A

    Solution :

    Key Idea: Equivalent conductance & conductance of all ions produced by one gram equivalent of electrolyte dissolved in \[V\,c{{m}^{3}}\]of solution. \[{{\Lambda }_{eq}}={{\kappa }_{c}}\times \frac{1000}{N}=\kappa \,V\] units of equivalent conductance \[{{\Lambda }_{eq}}\]are \[oh{{m}^{-1}}\,c{{m}^{2}}{{(g\,eq)}^{-1}}\].
