Exchange enthalpy

WebSep 2, 2024 · The heat exchange between a chemical reaction and its environment is known as the enthalpy of reaction, or H. However, H can't be measured directly — instead, scientists use the change in the temperature of a reaction over time to find the change in enthalpy over time (denoted as ∆H ). WebEnthalpy change is the sum of internal energy denoted by U and product of volume and Pressure, denoted by PV, expressed in the following manner. H=U+PV Enthalpy is also described as a state function completely …
