WebFor a reaction that has only starting materials, the product concentrations are [\text C]= [\text D]=0 [C] = [D] = 0. Since our numerator is zero, then Q=0 Q = 0. For a reaction that has only products, we have [\text A]= [\text … WebDec 3, 2015 · ΔG = ΔH − T ⋅ ΔS At standard state conditions, i.e. at a pressure of 1 atm, you can use the notation ΔG∘, ΔH ∘, and ΔS∘. Now, what does the sign of ΔG tell you? In order for a reaction to be spontaneous at a given temperature, you must have ΔG < 0. When ΔG > 0, the reaction is non-spontaneous.
