Enthalpy is often used to express the heat added to or removed from a substance during a process, especially when the process occurs at constant pressure. The enthalpy change of a substance during a chemical reaction is also crucial in understanding and predicting the heat of reaction. ...
The bond enthalpy Dx−yof a diatomic gas molecule XY is the enthalpy change for the process represented by the generic reaction: XY(g) → X(g) + Y(g) ΔH° (298 K) = Dx−y Any bond enthalpy formula is given at 298 K by convention to standardize the equation. This is approxima...
