WebAug 6, 2024 · It doesn't matter. Since Q = 1, the current state of the reaction is that E_(cell) = E_(cell)^@ and DeltaG = DeltaG^@. You should be able to prove that that is true, and it should take you less than 2 minutes. Calculate E_(cell)^@, like the question suggests. As I mentioned earlier, the no-brainer way is to subtract the less positive from the more … WebMar 6, 2024 · the value of Δ G ∘ = − n F E ∘ ( n = 2) actually refers to the value of Δ G ∘ for the reaction.
