Given the table below predict the numerical value of the standard cell potential for the reaction:

2 Cr(s) + 3 Cu2+(aq) → 2 Cr3+(aq) + 3 Cu(s)

Half Reaction (volts)
(1) Cr3+(aq) + 3 e-→ Cr(s) -0.74
(2) Cr3+(aq) + e-→ Cr2+(aq) -0.41
(3) Cr2O72-(aq) + 14 H+(aq) + 6 e-→ 2 Cr3+(aq) + 7 H2O(l) 1.33
(4) Cu+(aq) + e-→ Cu(s) 0.52
(5) Cu2+(aq) + 2 e-→ Cu(s) 0.34
(6) Cu2+(aq) + e-→ Cu+(aq) 0.16


▸ 2.50 volts

▸ 0.417 volts

▸ -1.08 volts

▸ 1.08 volts
