Question

Which of the following statements is correct for a reversible process in a state of equilibrium ?

• A. $\Delta G^{\circ }=2.30$ RT log K
• B. $\Delta G=-2.30$ RT log K
• C. $\Delta G=2.30$ RT log K
• D. $\Delta G^{\circ }=-2.30$ RT log K

Answer 1

The correct option is D

$\Delta G^{\circ }=-2.30$ RT log K

$\Delta G=\Delta G^{\circ }+2.303$ RT log K
At equilibrium, $\Delta G=0$
$0=\Delta G^{\circ }+2.303$ RT log K

$\Delta G^{\circ }=-2.303$ RT log K
