In a simple electrochemical cell, which is in standard state, half cell reactions with their appropriate oxidation potentials are
Pb (s) – 2e– \(\text { → }\) Pb2+ (aq) E0 = + 0.13 volt
Ag (s) – e– \(\text { → }\) Ag+ (aq) E0 = – 0.80 volt
Which of the following reaction takes place ?
Pb (s) – 2e– \(\text { → }\) Pb2+ (aq) E0 = + 0.13 volt
Ag (s) – e– \(\text { → }\) Ag+ (aq) E0 = – 0.80 volt
Which of the following reaction takes place ?
- Pb2+ (aq) + 2 Ag (s) → 2 Ag+ (aq) + Pb (s)
- Pb2+ (aq) + Ag (s) → Ag+ (aq) + Pb (s)
- Ag+ (aq) + Pb (s) → Ag (s) + Pb2+ (aq)
- 2 Ag+ (aq) + Pb (s) → 2Ag (s) + Pb2+ (aq)
Answer
(D) 2 Ag + (aq) + Pb (s) → 2Ag (s) + Pb 2+ (aq)
