WebDec 8, 2015 · Yes, at equilibrium, ΔrG = 0 and Q = K. However, everything after the first bullet point is wrong. You cannot conclude that ΔrG ∘ = 0, nor can you conclude that K = 1. The equation ΔrG ∘ = − RTlnK does not analogously translate into ΔrG = − RTlnQ! The accurate relation is: ΔrG = ΔrG ∘ + RTlnQ.
