Question

Assertion :$E_{cell}^o$ is an extensive property. Reason: $\frac{\Delta G^o}{n}$ is also an intensive property.

• 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. Assertion is incorrect but Reason is correct

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

The relationship between the standard free energy change and the standard cell potential is $-\Delta G^o=n{E}^{o}F$.
On rearranging this expression, w get, $\therefore E^o=\frac{-\Delta G^o}{nF}$.
Since, the standard gibbs free energy change is an intensive property, the standard cell potential is also an intensive property.
Hence, assertion is correct but Reason is incorrect.
