Which of the following statements is correct for a reversible process in a state of equilibrium? [NEET 2015 ]

A)  \[\Delta G=-2.30\,\,RT\,\,\,\log \,\,K\]

B)  \[\Delta G=2.30\,\,RT\,\,\,\log \,\,K\]

C)  \[\Delta {{G}^{o}}=-2.30\,\,RT\,\,\,\log \,\,K\]

D)  \[\Delta {{G}^{{}^\circ }}=2.30\,\,RT\,\,\,\log \,\,K\]

Correct Answer: C

Solution :

Mathematical expression of the thermodynamic equilibrium is

At equilibrium when  and Q = K

then
