Equivalent conductance $\left({\Lambda }_{\mathrm{eq}}\right)$ is defined as the conducting power of all the ions produced by one gram equivalent of an electrolyte in a given solution.in case of weak electrolytes (as ${\mathrm{CH}}_3\mathrm{COOH},{\mathrm{NH}}_4\mathrm{OH},\mathrm{AgCl}$ etc. $),$ ionisation is very small compared to strong electrolytes (as KCl, NaOH etc.), hence ${\Lambda }_{\text{oq }}$ of weak electrolyte is low. Moreover, ionisation of ${\mathrm{H}}^{\ast }$ is maximum among given ions. Thus, correct of order of ${\Lambda }_{\mathrm{eq}}$ is ${\mathrm{H}}^{+}>{\mathrm{OH}}^{-}>{\mathrm{K}}^{+}>{\mathrm{CH}}_3{\mathrm{COO}}^{-}$
