Using the following reduction half-reactions and their respective standard reduction potentials at 25 °C, draw a diagram of a galvanic cell.

Cr2O72-(aq) + 14 H+(aq) + 6e-→ 2 Cr3+(aq) + 7 H2O(l) = +1.33 V
Zn2+(aq) + 2 e-→ Zn(s) = -0.763 V

◦ Zn2+(aq) Zn(s), H+(aq) Cr2O72-(aq), Cr(s) Cr3+(aq)
◦ Zn(s) Zn2+(aq) H+(aq), Cr3+(aq) Cr(s)
◦ Cr(s) Cr3+(aq), H+(aq), Cr2O72-(aq) Zn(S) Zn2+(aq)
◦ Zn(s) Zn2+(aq) Cr2O72-(aq), H+(aq), Cr3+(aq) Pt(s)
◦ Pt(s) Cr3+(aq), Cr2O72-(aq), H+(aq) Zn2+(aq) Zn(s)
