Webb12 apr. 2024 · A standard state of a pure substance is a particular reference state appropriate for the kind of phase and is described by intensive variables. Webb24 mars 2024 · As explained in the comments, the standard state conditions lead to Q = 1 and therefore. Δ G = Δ G ∘ + R T ln 1 = Δ G ∘. On the other hand at equilibrium Q = K and so. Δ G = Δ G ∘ + R T ln K. This of course leads to Δ G ∘ = − R T ln K since at equilibrium Δ G = 0. So you might want to think of it as multiple statements:
