The following reaction has a E° cell value of 0.27 V:
Cu2+(aq) + 2 Ag(s) + 2Br-(aq) ® Cu(s) + 2AgBr(s)
1. Determine the standard reduction potential for the half-reaction, AgBr(s) + e- ®Ag(s) + Br-(aq).
2. Calculate the equilibrium constant to support your answer. Is the overall cell reaction reactant or product favored at 25°C?
