The value of
Explanation of Solution
Given:
The half reactions of standard galvanic cell as:
The reduction potential values for the half reactions of standard galvanic cell is:
Since, the reduction potential value of silver is greater than copper so, the silver will undergo reduction and copper will undergo oxidation so, the half-reactions are written as:
To balance the charge on both sides, the reduction reaction,
Adding both the reactions to get the overall reactions as:
So, the overall balanced reaction for the galvanic cell is:
