Question 1

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

Mg(s) + Cu2+(aq) → Cu(s) + Mg2+(aq)

Mg2+(aq) + 2 e⁻ → Mg(s)

E° = -2.38 V

Cu2+(aq) + 2 e⁻ → Cu(s)

E° = +0.34 V

◦ -2.04 V
◦ +1.36 V
◦ +2.04 V
◦ +2.72 V
◦ -1.36 V

Question 2

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

2K(s) + I2(s) → 2K⁺(aq) + 2I⁻(aq)

K+(aq) + e⁻ → K (s)

E° = -2.93 V

I2(s) + 2 e⁻ → 2 I⁻(aq)

E° = +0.54 V

◦ +1.85 V
◦ +5.32 V
◦ +3.47 V
◦ -5.32 V
◦ +6.40 V
