Question 45

Multiple Choice

Determine Ecell at 25 °C for the following reaction at 25 °C:
Al(s) ∣ Al3+(0.435 M) Determine E<sub>cell</sub> at 25 °C for the following reaction at 25 °C: Al(s) ∣ Al<sup>3+</sup>(0.435 M)    Sn<sup>2+</sup>(2.12 × 10<sup>-3</sup> M) ∣ Sn(s)  3 Sn<sup>2+</sup>(aq) + 2 Al(s) → 2 Al<sup>3+</sup>(aq) + 3 Sn(s)  Al<sup>3</sup><sup>+</sup>(aq) + 3 e<sup>-</sup> → Al(s) E° = -1.676 V Sn<sup>2+</sup>(aq) + 2 e<sup>-</sup> → Sn(s) E° = -0.137 V A) 1.227 V B) 1.611 V C) 1.562 V D) 1.487 V E) 1.467 V Sn2+(2.12 × 10-3 M) ∣ Sn(s)
3 Sn2+(aq) + 2 Al(s) → 2 Al3+(aq) + 3 Sn(s)
Al3+(aq) + 3 e- → Al(s) E° = -1.676 V
Sn2+(aq) + 2 e- → Sn(s) E° = -0.137 V


A) 1.227 V
B) 1.611 V
C) 1.562 V
D) 1.487 V
E) 1.467 V
