The cell in which the following reaction occurs :                 2Fe3+ (aq) + 2I? (aq)  2Fe2+ (aq) + I2(s)                 has E0cell = 0.236 V at 298 K. Calculate the standard Gibb's energy and the equilibrium constant of the cell reaction.  

Answer:

Kc = antilog (8.0) = 1 × 108             = ? 2 × 96500 C × (0.236 V) = ? 45548 J mol?1   = ? 45.548 kJ mol?1.
