Question

Assertion :$E_{cell}^{\circ }$ is negative for electrolytic cell. Reason: $△G^{\circ }$ is positive for electrolytic cell.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

This cell converts electric energy into chemical energy.
As this process is a non-spontaneous reaction so $△G^{\circ }$ is positive for electrolytic cell.

And as,

$\Delta G^0=-nF{E}^0$ so

$E_{cell}^{\circ }$ is negative for electrolytic cell.
