Question

Consider the following standard reduction potentials:
2H⁺(aq) + 2e^-

Consider the following standard reduction potentials: 2H<sup>+</sup>(aq) + 2e<sup>-</sup> H<sub>2</sub>(g) ; E° = 0.00 V Sn<sup>2+</sup>(aq) + 2e<sup>-</sup> Sn(s) ; E° = -0.15 V Cd<sup>2+</sup>(aq) + 2e<sup>-</sup> Cd(s) ; E° = -0.40 V Which pair of substances will react spontaneously under standard-state conditions? A) Cd with H<sup>+</sup> B) Cd with Sn C) Sn<sup>2+</sup> with Cd<sup>2+</sup> D) Sn with Cd<sup>2+</sup> E) Sn<sup>2+</sup> with H<sup>+</sup>

H₂(g) ; E° = 0.00 V
Sn²⁺(aq) + 2e^-

Sn(s) ; E° = -0.15 V
Cd²⁺(aq) + 2e^-

Cd(s) ; E° = -0.40 V
Which pair of substances will react spontaneously under standard-state conditions?
