The cell in which the following reaction occurs : 2Fe^3+(aq) + 2I^-(aq) → 2Fe^2+(aq) + I2(*) has E°cell = 0.236 V at 298K.

Question 1

The cell in which the following reaction occurs :

2Fe3+(aq) + 2I-(aq) → 2Fe2+(aq) + I2() has E°cell = 0.236 V at 298K. Calculate the standard Gibb' energy and the equilibrium constant of the cell reaction.

(Antilog of 6.5 = 3.162 x 106; of 8.0 = 10 x 108; of 8.5 = 3.162 x 108)

Question 2

△rG° = -nFE°cell

= -2 x 96500 x 0.236

= 45.548 kJ/mol

The cell in which the following reaction occurs : 2Fe^3+(aq) + 2I^-(aq) → 2Fe^2+(aq) + I2(*) has E°cell = 0.236 V at 298K.
