WebDec 8, 2015 · The equation ΔrG ∘ = − RTlnK does not analogously translate into ΔrG = − RTlnQ! The accurate relation is: ΔrG = ΔrG ∘ + RTlnQ Setting Q = K and ΔrG = 0 in this equation does not tell you anything about the value of K. In fact, if you try doing it, all you will find out is that ΔrG ∘ = − RTlnK - no surprises there!
