Consider a galvanic electrochemical cell constructed using Cr/Cr3+ and Zn/Zn2+ at 25 °C. The following half-reactions are provided for each metal: Cr3+(aq) + 3 e → Cr(s) Eºred = -0.744 V Zn2+(aq) + 2e → Zn(s) Eºred = -0.763 V V 1 2 3 Х Given that the standard cell potential is 0.019 V and the overall equation is 2 Cr3+ (aq) + 3 Zn (s) → 2 Cr (s) + 3 Zn2+ (aq), what is the cell potential for this cell at 25 °C when [Zn2+] = 0.0263 M and [Cr3+] = 0.1676 M? - 4 5 6 C 7 8 +/- 0 O . x 100 +
