Answer:
The reaction with smallest value of K is :
A + B → 2 C; E°cell = -0.030 V
Explanation:
where :
n = number of electrons transferred
F = Faraday's constant = 96500 C
= standard electrode potential of the cell
R = Gas constant = 8.314 J/K.mol
T = temperature of the reaction =
= equilibrium constant of the reaction
As we cans see, that standard electrode potential of the cell is directly linked to the equilibrium constant of the reaction.
- Higher
higher will be the value of K.
- Lower
So, the reaction with smallest value of electrode potential will have smallest value of equilibrium constant. And that reaction is:
A + B → 2 C;
