WebJan 21, 2024 · 1 Consider a reaction (R1) A + B ↽ − − ⇀ C + D. Now Δ G for the forward reaction is (1) Δ G f w d = Δ H − T Δ S. For the reverse reaction Δ H and Δ S are clearly the same in magnitude but opposite in sign. Therefore, (2) Δ G rev = − Δ G fwd, which implies that if the forward reaction is feasible, then the reverse isn’t and vice versa. kitchenaid chopper dishwasher partWebAug 13, 2024 · The forward reaction is the exothermic direction: the formation of NH 3 releases heat which is why that is shown as a product. The reverse reaction is the endothermic direction: as NH 3 decomposes to N 2 and H 2, heat is absorbed.
