Reason : On increasing dilution, degree of ionisation of weak electrolyte increases and molality of ions also increases.
[At $45^{\circ} \mathrm{C}$ vapour pressure of benzene is $280\, \mathrm{~mm} \,\mathrm{Hg}$ and that of octane is $420\, \mathrm{~mm} \,\mathrm{Hg}$. Assume Ideal gas]

$Zn | ZnSO_4 \,(0.01\, M) | | CuSO_4\,(1.0\, M) | Cu$
When the concentration of $ZnSO_4$ is $1.0\,M$ and that of $CuSO_4$ is $0.01\,M$, the $emf$ changed to $E_2$ What is the relation between $E_1$ and $E_2$?
