question 16

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.)
$\quad$$\quad$ 2K(s) + I₂(s) → 2K⁺ (aq) + 2I^- (aq)
K⁺(aq) + e^- → K (s) $\quad$ E° = -2.93 V
I₂(s) + 2 e^- → 2 I^- (aq) $\quad$ E° = +0.54 V
