WebOct 28, 2024 · ΔH for a reaction is equal in magnitude but opposite in sign to ΔH for the reverse reaction. For example: HgO (s) → Hg (l) + ½ O 2 (g); ΔH = +90.7 kJ. Hg (l) + ½ O 2 (l) → HgO (s); ΔH = -90.7 kJ. This law is commonly applied to phase changes, although it is true when you reverse any thermochemical reaction. ΔH is independent of the ... WebIn chemistry, the system almost always refers to a given chemical reaction and the container in which it takes place. The first law of thermodynamics tells us that energy can neither be created nor destroyed, so we know that the energy that is absorbed in an endothermic chemical reaction must have been lost from the surroundings. numbers on the camera lens
