    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, is 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 \[oh{{m}^{-1}}c{{m}^{2}}{{(g\,\,eq)}^{-1}}\]or \[S\,c{{m}^{2}}e{{q}^{-1}}\]
