since \(\Delta G=-n F E^{\circ}\)
Hence for \(\Delta G\) to be \(-v e \Delta E^{\circ}\) has to be positive.
Which is possible when \(X=Z n, Y=N i\)
\(Z n+N i^{++} \longrightarrow Z n^{++}+N i\)
\(E_{Z n / Z n^{+2}}^{\circ}+E_{N i^{2+} / N i}^{\circ}\)
\(=0.76+(-0.23)=+0.53(\text { positive })\)
$\Lambda _{C{H_3}COONa}^o =91.0\, S \,cm^2 /equiv.$
$\Lambda _{HCl}^o =426.2 \,S \,cm^2 /equiv.$
તો એસિટીક એસિડના જલીય દ્રાવણ ${\Lambda ^o}$ ગણવા કઈ વધારાની માહિતી/જથ્થો જોઈએ ?
