The limiting ionic conductivity ( $\Lambda 0$ ) values (in $mS m ^2 mol ^{-1}$ ) for different ions in aqueous solutions are given below:
| Ions | $Ag ^{+}$ | $K ^{+}$ | $Na ^{+}$ | $H ^{+}$ | $NO _3^{-}$ | $CI ^{-}$ | $SO _4^{2-}$ | $OH ^{-}$ | $CH_3COO ^{-}$ |
| $\Lambda_0$ | $6.2$ | $7.4$ | $5.0$ | $35.0$ | $7.2$ | $7.6$ | $16.0$ | $19.9$ | $4.1$ |
For different combinations of titrates and titrants given in $List-l$, the graphs of 'conductance' versus 'volume of titrant' are given in $List-II$.
Match each entry in $List-I$ with the appropriate entry in $List-II$ and choose the correct option.
| $(IE_1 + IE_2)$ | $(IE_3 + IE_4)$ |
| $(P)$ $2.45\, KJ/mol$ | $8.82\, KJ/mol$ |
| $(Q)$ $2.85\, KJ/mol$ | $6.11\, KJ/mol$ |
then according to given information the incorrect statements is/are
Above conversion can be achieved by
