Enthalpy /ˈɛnθəlpi/ (listen), a property of a thermodynamic system, is the sum of the system's internal energy and the product of its pressure and volume. It is a state function used in many measurements in chemical, biological, and physical systems at a constant pressure, which is conveniently provided by the large ambient atmosphere. The pressure–volume term expresses the work required t… WebThis is the enthalpy change for the exothermic reaction: C(s) + O2(g) CO2(g) ΔH ° f = ΔH° = −393.5kJ. starting with the reactants at a pressure of 1 atm and 25 °C (with the carbon …
