What will be standard cell potential of galvanic cell with the following reaction?
2Cr(s) + 3Cd2+(aq) → 2Cr3+(aq) + 3Cd(s)
[Given: E°Cr3+/Cr = –0.74 V and E°Cd2+/Cd = –0.40 V]
2Cr(s) + 3Cd2+(aq) → 2Cr3+(aq) + 3Cd(s)
[Given: E°Cr3+/Cr = –0.74 V and E°Cd2+/Cd = –0.40 V]
- 0.74 V
- 1.14 V
- 0.34 V
- – 0.34 V
Answer
(C) 0.34 V
