WebA relationship between q and ΔH can be defined knowing whether q is endothermic or exothermic. An endothermic reaction is the one that absorbs heat and reveals that heat is consumed in the reaction from the surroundings, hence q>0 (positive). If q is positive, then ΔH is also positive, at constant pressure and temperature for the above equation. WebJan 4, 2024 · Enthalpy is a thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system. It reflects the capacity to do non-mechanical work and the capacity to release heat . Enthalpy is denoted as H; specific enthalpy denoted as h. Common units used to express enthalpy are the …
