If the standard free energy change () for a chemical equilibrium reaction is exactly zero, what is t — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The standard free energy change is related to the equilibrium constant by the isotherm equation $\Delta G^\circ = -RT \ln K_p$. If $\Delta G^\circ = 0$, then $-RT \ln K_p = 0$, which implies $\ln K_p = 0$. Therefore, $K_p = e^0 = 1$.
