MCQ
The solubility of $AgCl$ is minimum in
- A$AgNO_3\,(0.1\,M)$
- ✓$H_2O\,(l)$
- C$NaCl\,(0.4\,M)$
- D$BaCl_2\,(0.3\,M)$
$\mathop {BaC{l_2}}\limits_{0.3} \to B{a^{2 + }} + \mathop {2C{l^ - }}\limits_{0.6\,M} $
$\mathop {AgN{O_3}}\limits_{0.1} \to A{g^ + } + \mathop {NO_3^ - }\limits_{0.1} $
$\mathop {NaCl}\limits_{0.4} \to N{a^ + } + \mathop {C{l^ - }}\limits_{0.4} $

$3 HC \equiv CH _{( g )} \rightleftharpoons C _{6} H _{6(\ell)}$
[Given: $\Delta_{f} G ^{\circ}( HC \equiv CH )=-2.04 \times 10^{5}\, J mol ^{-1}$
$\Delta_{f} G ^{\circ}\left( C _{6} H _{6}\right)=-1.24 \times 10^{5}\, J mol ^{-1} ; R =8.314\,\left. J K ^{-1} mol ^{-1}\right]$
