The $\mathrm{Zn^{2+} \mid Zn}$ half cell ($\mathrm{E^{\circ} = -0.762\,V}$) is connected to a $\mathrm{Cu^{2+} \mid Cu}$ half cell ($\mathrm{E^{\circ} = 0.340\,V}$). What is the value of $\mathrm{E^{\circ}_{cell}}$ for spontaneous conversion of chemical energy to electrical energy? What is the value of $\log_{10}\mathrm{K}$, where K is the equilibrium constant? Use $(2.303\,RT/F) = 0.06$.
