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


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