Equivalent conductance $\left( \Lambda _{e q}\right)$ is defined as the conducting power of all the ions produced by one gram equivalent of an electrolyte in a given solution.ln case of weak electrolytes (as $CH _{3} COOH _{1} NH _{4} OH , AgCl$ etc.), ionisation is very
small compared to strong electrolytes (as $KCl$, $NaOH$ etc.), hence $\Lambda_{\text {eq }}$ of weak electrolyte is low. Moreover, ionisation of $H ^{+}$is maximum among given ions. Thus, correct of order of $\Lambda _{\text {eq }}$ is
$ H ^{+}> OH ^{-}> K ^{+}> CH _{3} COO ^{-} $
