Question

The correct relationship between free energy change in a reaction and the corresponding equilibrium constant $K_{c}$ is:

• A. $\Delta G=R T$ ln $K_{c}$
• B. $-\Delta G=R T$ ln $K_{c}$
• C. $\Delta G^{\circ}=R T$ ln $K_{c}$
• D. $-\Delta G^{\circ}=R T$ ln $K_{c}$

Answer 1

Answer: (D)

$-\Delta G^{\circ}=R T$ ln $K_{c}$

Answer 2

$\Delta G^{\circ}=-W_{\max }$. Maximum work done by the system.
