Question

Assertion :At equilibrium $\Delta G=0$ Reason: $\Delta G^o=-RT{\log }_e{K}_c$ at equilibrium

• 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 B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

At equilibrium $\Delta G=0$
$\Delta G^o=-RT{\log }_e{K}_c$ at equilibrium
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Note ;
$\Delta G=\Delta G^o+RT{\log }_e{K}_c$
Substitute $\Delta G=0$ for equilibrium conditions
$0=\Delta G^o+RT{\log }_e{K}_c$
$\Delta G^o=-RT{\log }_e{K}_c$
