The change in enthalpy for a reaction can be calculated by subtracting the sum of the enthalpies of formation of all the changes from the sum of the enthalpies of formation of all the changes.
Enthalpy is a property or state function that resembles energy; it has the same dimensions as energy and is therefore measured in joules or ergs. The value of enthalpy is solely dependent on the temperature, pressure, and composition of the system, not on its history.
Enthalpy is the unit used to describe the total amount of heat in a thermodynamic system with constant pressure. It's depicted as. Where E is the internal energy, P is the pressure, and E is the energy, H is defined as E + P + V.
Enthalpy is a system's thermodynamic attribute. It is made up of the system's pressure, volume, and internal energy put together. It displays both the ability to produce heat and the ability to perform the non-mechanical activity.
