Answer:

2.49 V.

Explanation:

The formula which relates the equilibrium condition in the electrochemical cell is,

logk_{eq}=\frac{n}{0.059}  E_{cell} ^{0}

Given that the number of electron is 3 and the value of E^{0} _{cell} is  0.652 V.

Now put these values in above equation.

logk_{eq}=\frac{3}{0.059}  (0.652 V)\\logk_{eq}=33.15 V\\k_{eq}=e^{33.15}V\\k_{eq}=2.49V

Therefore, the value of Keq for an electrochemical reaction is 2.49 V.
