STATEMENT-1: We cannot add the electrode potential in order to get electrode potential of third electrode if no. of moles of electrons exchanged are not same.
STATEMENT-2: Electrode potential is an extensive property

Options

A. If both the statements are TRUE and STATEMENTS-2 is the correct explantion of STATEMENTS-9
B. If both the statements are TRUE but STATEMENTS-2 is NOT the correct explanation of STATEMENTS-11
C. If STATEMENTS-1 is TRUE and STATEMENTS-2 is FALSE
D. If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE

Answer

To solve the given question, we will analyze both statements provided and determine their validity based on the principles of electrochemistry.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- The statement claims that we cannot add the electrode potentials of two half-cells to find the electrode potential of a third electrode if the number of moles of electrons exchanged are not the same.
- In electrochemistry, the electrode potential (E) is related to the number of moles of electrons (n) transferred in a reaction. If different reactions involve different numbers of electrons, their potentials cannot be directly added because they do not represent the same amount of charge transfer.

2. **Understanding Statement 2**:
- The second statement claims that electrode potential is an extensive property.
- An extensive property depends on the amount of substance present, while an intensive property does not. Electrode potential is actually an intensive property, as it does not depend on the quantity of the material involved in the electrochemical reaction.

3. **Analyzing the Truth of Each Statement**:
- **Statement 1** is true: We cannot simply add electrode potentials when the number of moles of electrons exchanged differs.
- **Statement 2** is false: Electrode potential is an intensive property, not an extensive one.

4. **Conclusion**:
- Since Statement 1 is true and Statement 2 is false, we conclude that the correct answer is that Statement 1 is true and Statement 2 is false.

### Final Answer:
- **Statement 1**: True
- **Statement 2**: False
- Therefore, the answer is that Statement 1 is true and Statement 2 is false.
