हिन्दीFor a reaction in equilibrium, the relationship between the standard Gibbs energy change \( \Delta_r G^\circ \) and the equilibrium constant \( K \) is given by:
Correct answer · Option 2
\( \Delta_r G^\circ = -2.303 RT \log K \)
Explanation
At equilibrium, \( \Delta_r G = 0 = \Delta_r G^\circ + RT\ln K \implies \Delta_r G^\circ = -RT\ln K = -2.303 RT\log K \).
