Answer:

0.46V

Explanation:

This problem requires us to find the cell potential under conditions other than standard conditions. The cell potential for various systems under standard conditions are easily obtained from reduction potential tables. However, under nonstandard conditions, the cell potential is obtained from Nernst equation provided the relative concentration of individual species and the standard cell potential is supplied.

Nernst equation was applied in the detailed solution attached
