$Cu(s) + 2Ag{^+}_{(aq)} \to Cu^{+2}_{(aq)} + 2Ag(s)$
માટે સંતુલન અચળાંક $K_C = 10 \times 10^{15}$ છે, તો $298\, K$ ને $E_{cell}^o$ નું મૂલ્ય કેટલુ થશે?
[${2.303\,\frac{{RT}}{F}}$ એ $298\,K$ $=0.059\,V$]
\(2FE_{cell}^o\, = \,2.303\,RT\,\log \,{K_{eq}}\)
\(2E_{cell}^o\, = \,\frac{{2.303\,RT}}{F}\,\log \,10\, \times \,{10^{15}}\)
\(E_{cell}^o\, = \,\frac{{0.059}}{2}\,\, \times \,16\) \( = \,8\, \times \,0.059\, \Rightarrow \,0.472\)
