question 107

Multiple Choice

Consider the following reduction potentials:
Cd²⁺(aq) + 2e^- Cd(s) ; E° = -0.40 V
Pb²⁺(aq) + 2e^- Pb(s) ; E° = -0.13 V
Cu²⁺(aq) + 2e^- Cu(s) ; E° = 0.34 V
Br₂(l) + 2e^- 2Br^-(aq) ; E° = 1.07 V
Under standard-state conditions,which of the following reactions is spontaneous?

• A)Cd²⁺(aq)+ Pb(s)→ Cd(s)+ Pb²⁺(aq)
• B)Pb²⁺(aq)+ Cu(s)→ Pb(s)+ Cu²⁺(aq)
• C)2Br^-(aq)+ Pb²⁺(aq)→ Br₂(l)+ Pb(s)
• D)2Br^-(aq)+ Cu²⁺(aq)→ Br₂(l)+ Cu(s)
• E)Cu²⁺(aq)+ Cd(s)→ Cu(s)+ Cd²⁺(aq)
