Products of electrolysis depend on the nature of material being electrlysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. thus, the products of electrolysis may be different for reactive and inert electrodes.
Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells.
In these question, a statement of assertion followed by a statement of reason. choose the correct answer out of the following choices.
Q. Assertion (A): At equilibrium condition `E_(cell)=0` or `Delta_(r)G=0`.
Reason (R): `E_(cell)` is zero when both electrodes of the cell are of the same metal.

Options

A. Assertion and Reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement butreason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Explanation

To solve the question, we need to analyze the assertion and reason provided, and determine their correctness.

### Step 1: Analyze the Assertion
The assertion states that at equilibrium conditions, \( E_{\text{cell}} = 0 \) or \( \Delta_r G = 0 \).

- This is correct. At equilibrium, the cell does not perform any work, and hence the cell potential \( E_{\text{cell}} \) becomes zero. Additionally, the Gibbs free energy change \( \Delta_r G \) is also zero at equilibrium, indicating that there is no net change in the system.

### Step 2: Analyze the Reason
The reason states that \( E_{\text{cell}} \) is zero when both electrodes of the cell are of the same metal.

- This statement is also correct. When both electrodes are made of the same metal, their standard electrode potentials \( E^0 \) are equal. Therefore, the overall cell potential \( E_{\text{cell}} \) becomes zero, as the potential difference between the two electrodes is nullified.

### Step 3: Determine the Relationship Between Assertion and Reason
Now we need to determine if the reason correctly explains the assertion.

- While both the assertion and reason are correct, the reason does not directly explain the assertion. The assertion refers to the condition of equilibrium in a general sense, while the reason specifically addresses the scenario of identical electrodes. Therefore, the reason does not provide a comprehensive explanation for the assertion.

### Conclusion
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion. Thus, the correct answer is:

**Option 2: Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion.**
