330463 In a cell that utilises the reaction
\(\mathrm{Zn}(\mathrm{s})+2 \mathrm{H}^{+}(\mathrm{aq}) \rightarrow \mathrm{Zn}^{2+}(\mathrm{aq})+\mathrm{H}_{2}(\mathrm{~g})\)
addition of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) to cathode compartment, will

1 increase the E and shift equilibrium to the right.
2 lower the \(E\) and shift equilibrium to the right.
3 lower the E and shift equlibrium to the left.
4 increase the \(\mathrm{E}\) and shift equilibrium to the left.
CHXII03:ELECTROCHEMISTRY

330464 Statement A :
On increasing dilution, the specific conductance keep on increasing.
Statement B :
On increasing dilution, degree of ionisation of weak electrolyte increases and molar conductivity increases.
