WebNov 2, 2024 · As enthalpy is a state function, change in enthalpy (ΔH) will depend on the initial and the final states of the system. ΔH = H 2 – H 1. Here, H 1 is the enthalpy of the system in the initial state and H 2 is the enthalpy of the system in the final state. So if we write the enthalpy’s formula ( H = U + PV ) in a similar form. WebThe enthalpy of reaction is defined as the internal energy of the reaction system, plus the product of pressure and volume. It is given by: H=U+PV H = U +P V. By adding the PV term, it becomes possible to measure a change in energy within a chemical system, even when that system does work on its surroundings. free printable awards pdf https://accweb.net
