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
