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) E°red = -0.744 V Zn²⁺(aq) + 2 e⁻ → Zn(s) E°red = -0.763 V

which half reaction takes place at the anode

which is the standar cell potential

write the balance equation for the overall reaction in acidic sol

What is the cell potential for this cell at 25 °C when [Zn²⁺] = 0.0343 M and [Cr³⁺] = 0.1756 M?
