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.
So, the reaction with smallest value of electrode potential will have smallest value of equilibrium constant. And that reaction is:
A + B → 2 C;
Answer:
Explanation:
Hello,
In this case, for the given reaction at equilibrium:
We can write the law of mass action as:
That in terms of the change due to the reaction extent we can write:
Nevertheless, for the carbon monoxide, we can directly compute as shown below:
Finally, we can compute the equilibrium constant:
Best regards.
