Assertion:Electrolytic cell uses electrical energy to carry non-spontaneous chemical reactions.
Reason : Chemical energy of a spontaneous redox reaction can be converted into electrical energy.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion .
B. If both assertion and reason are true but reason is not the correct explanation of assertion .
C. If assertion is true but reason is false .
D. If both assertion and reason are false .

Answer

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

### Step 1: Analyze the Assertion
The assertion states: "Electrolytic cell uses electrical energy to carry non-spontaneous chemical reactions."

- **Explanation**: An electrolytic cell indeed uses electrical energy to drive chemical reactions that do not occur spontaneously. This is a fundamental characteristic of electrolytic cells, where an external source of electricity is required to initiate and sustain the reaction.

**Conclusion**: The assertion is **True**.

### Step 2: Analyze the Reason
The reason states: "Chemical energy of a spontaneous redox reaction can be converted into electrical energy."

- **Explanation**: This statement is true as well. In galvanic cells (also known as voltaic cells), spontaneous redox reactions occur, and the energy released from these reactions can be harnessed to produce electrical energy. This is the principle behind how galvanic cells work.

**Conclusion**: The reason is **True**.

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

- The assertion is about electrolytic cells and their use of electrical energy for non-spontaneous reactions.
- The reason discusses galvanic cells and the conversion of chemical energy from spontaneous reactions into electrical energy.

**Conclusion**: While both the assertion and reason are true, the reason does not explain the assertion. The reason pertains to a different type of cell (galvanic) rather than the electrolytic cell mentioned in the assertion.

### Final Answer
Based on the analysis:
- Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

The correct option is: **Second** - "If both assertion and reason are true but reason is not the correct explanation of assertion."
