\({E_{cell}}\, = \,\,E_{cell}^ o  - \frac{{0.0591V}}{2}\,\,\log \,\,\frac{{[Z{n^{2 + }}(aq)]}}{{[C{u^{2 + }}(aq)]}}\)

અહીં \( E_{cell} = 1.3 \,V, [Cu^{2+} (aq)] = 1.0\, M, [Zn^{2+}(aq)] = 0.1 M, E^o_{cell} = ?\) કિંમત મુકતા

\(1.3\,\,V\,= \,E_{cell}^ o - \,\frac{{0.0591V}}{2}\,\,\log \,\,\frac{{0.1}}{{1.0}}\)

\(1.3\,\,V\,= \,E_{cell}^o  - \,\,0.02955\,\,V\,\log \,\,{10^{ - 1}}\)

\(1.3\,\,V\,\, = \,E_{cell}^o  + 0.02955\,\,V\,\,\log \,10\)

\(E_{cell}^ o  = \,1.3\,\,V\, - \,\,0.02955\,\,V\,\, = \,\,1.27\,V\)
