Given the following standard reduction potentials, which reaction would be expected to occur?
Cu+ + e− → Cu (s) E° = +0.52 V
2H+ + 2e− → H2 (g) E° = 0 V
Pb2+ + 2e− → Pb (s) E° = −0.13 V
Cr3+ + e− → Cr2+ E° = −0.41 V
(A) 2Cu (s) + Pb2+ → 2Cu+ + Pb (s)
(B) Pb2+ + H2 (g) → Pb (s) + 2H+
(C) 2Cr2+ + Pb2+ → Pb (s) + 2Cr3+
(D) Pb (s) + 2Cr3+ → 2Cr2+ + Pb2+
