Calculate the Cell Potential for the Following Unbalanced Reaction That $\mathrm { Cr } ^ { 3 }$

Calculate the cell potential for the following unbalanced reaction that takes place in an electrochemical cell at 25 °C when [ $\mathrm { Cr } ^ { 3 }$ ] = 0.945 M and [ $\mathrm { Zn } ^ { 2 + }$ ] = 1.37 M
$\quad$$\quad$ Zn(s) + $\mathrm { Cr } ^ { 3+ }$ (aq) ? $\mathrm { Zn } ^ { 2 + }$ (aq) + Cr(s)
E°(Zn²⁺/Zn) = -0.76 V and E°(Cr³⁺/Cr) = -0.73 V

A) +0.03 V
B) -0.03 V
C) -1.18 V
D) +1.18 V
E) +0.49 V
