Question

The standard free energy change $(\Delta G^{\circ})$ is related to equilibrium constant $(K)$ as

• A. $\Delta G^{\circ} = -2.303RT\ln K$
• B. $\Delta G^{\circ} = 2.303RT\log K$
• C. $\Delta G^{\circ} = RT\log K$
• D. $\Delta G^{\circ} = -2.303RT\log K$

Hint:

$\Delta G^{\circ} = -RT \ln K$.

Answer 1

The Correct Option is D

Step 1: Conceptual Understanding:
$\Delta G^{\circ} = -RT \ln K$.
Step 2: Explanation in Detail:
$\Delta G^{\circ} = -RT \ln K = -2.303 RT \log K$.
Step 3: Therefore, Stating the Final Answer
$\Delta G^{\circ} = -2.303RT\log K$.
