The voltaic cell described by the balanced chemical reaction has a standard emf of 4.05 V. Calculate the equilibrium constant (Kc) for the reaction at 25 oC. Round your answer to 3 significant figures.

F2(g) + Mn(s) → 2F-(aq) + Mn2+(aq)


Mn2+/Mn -1.18
F2/F- +2.87

0 °C = 273.15 K
R = 8.314 J/(K x mol)


Faraday's Constant
96485 C/mol
