<u>Answer:</u> The of the reaction is 0.78 V and
respectively.
<u>Explanation:</u>
For the given half reactions:
Oxidation half reaction:
Reduction half reaction:
Net reaction:
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate equilibrium constant, we use the relation between Gibbs free energy, which is:
and,
Equating these two equations, we get:
where,
n = number of electrons transferred = 2
F = Faraday's constant = 96500 C
= standard electrode potential of the cell = 0.78 V
R = Gas constant = 8.314 J/K.mol
T = temperature of the reaction =
= equilibrium constant of the reaction = ?
Putting values in above equation, we get:
Hence, the of the reaction is 0.78 V and
respectively.
