Use the Standard Half-Cell Potentials Listed Below to Calculate the Standard

question 18

Multiple Choice

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.) 2 K(s) + I₂(s) → 2 K⁺(aq) + 2 I⁻(aq)
K⁺(aq) + e⁻ → K(s) E° = -2.93 V
I₂(s) + 2 e⁻ → 2 I⁻(aq) E° = +0.54 V

• A) +6.40 V
• B) +1.85 V
• C) -5.32 V
• D) +3.47 V
• E) +5.32 V
