The following half-reactions combine to make an electrolytic cell:
K+ (aq) + e- → K (s) E° = −2.93
Li+ (aq) + e- → Li (s) E° = −3.05
If a current of 1.5 Amps is placed on this cell for 5 minutes, which of the following describes the mass of solid formed (in grams) and the voltage required of the current.
[1 Amp = 1 coul/s; 96500 coul = 1 mol e-]
A. 0.0324 g; - 0.12 V
B. 0.000539 g ; - 0.12 V
C. 0.00466 g; 0.12 V
D. 0.0324 g; 5.98 V
E. 0.00466 g; 5.98 V
