Question

Use standard reduction potentials to calculate the standard free energy change in kJ for the reaction: Pb$^{2+}$(aq) + 2Cu$^{+}$(aq) ? Pb(s) + 2Cu$^{2+}$(aq) Pb$^{2+}$(aq) + 2e$^-$ ? Pb(s) $E^o_{red}$ = -0.126 V Cu$^{2+}$(aq) + e$^-$ ? Cu$^{+}$(aq) $E^o_{red}$ = 0.153 V ?G$^o$ = kJ K for this reaction would be than one.

          Use standard reduction potentials to calculate the standard free energy change in kJ for the reaction:

Pb$^{2+}$(aq) + 2Cu$^{+}$(aq) ? Pb(s) + 2Cu$^{2+}$(aq)

Pb$^{2+}$(aq) + 2e$^-$ ? Pb(s)  $E^o_{red}$ = -0.126 V
Cu$^{2+}$(aq) + e$^-$ ? Cu$^{+}$(aq)  $E^o_{red}$ = 0.153 V

?G$^o$ = ____ kJ

K for this reaction would be ____ than one.

Use standard reduction potentials to calculate the standard free energy change in kJ for the reaction:

Pb^2+(aq) + 2Cu^+(aq) ? Pb(s) + 2Cu^2+(aq)

Pb^2+(aq) + 2e^- ? Pb(s) E^ored = -0.126 V
Cu^2+(aq) + e^- ? Cu^+(aq) E^ored = 0.153 V

?G^o = kJ

K for this reaction would be than one.
