Enthalpy (H) is a thermodynamic quantity representing the total heat content of a system at constant pressure. Changes in enthalpy (ΔH) during a reaction indicate heat absorbed or released. Standard enthalpy of formation (ΔHf°) values allow calculation of ΔH for complex reactions. Understanding enthalpy is essential for controlling reaction conditions in fields like chemical engineering, where heat management is critical.
