17 20.4 THERMODYNAMICS AND THE EQUILIBRIUM CONSTANT At equilibrium, ΔG T = 0, and ΔG T o = -RT ln K T Figure 20.11, shows the relationship between Q and K, which comes from the concentration dependence of Free Energy.Figure 20.11, shows the relationship between Q and K, which comes from the concentration dependence of Free Energy.Figure 20.11Figure 20.11 One cannot calculate a new K by simply changing the T in the equation since ΔG T o is a function of temperature.One cannot calculate a new K by simply changing the T in the equation since ΔG T o is a function of temperature.
