The following half-cell reactions are used in a certain voltaic cell:
Br2(l) + 2 e– → 2 Br–(aq) E°red = 1.07 V
Ag+(aq) + e– → Ag(s) E°red = 0.80 V
If the concentrations of Br–(aq) and Ag+(aq) at 298 K are 0.015 M and 0.10 M respectively, calculate the emf generated by this cell at these concentrations.
