Question
What is the emf at 25oC for the cell, Ag
Pt
The standard reduction potentials for the half-reactions AgBr + e- → Ag + Br- and Fe3+ + e- → Fe2+ are + 0.0713 V and + 0.770 V respectively.
The standard reduction potentials for the half-reactions AgBr + e- → Ag + Br- and Fe3+ + e- → Fe2+ are + 0.0713 V and + 0.770 V respectively.
Options
A.0.474 volt
B.0.529 volt
C.0.356 volt
D.0.713 volt
Solution
Ecell = (0.77 - 0.0713) -
= 0.713 volt.
