The energy to do work in a reaction is called enthalpy.
It is considered to be the sum of the system's internal energy which is added to pressure and volume that is exerted on the system. Hence, enthalpy is the capability to release heat from the system and to do non-mechanical related work. The formula for enthalpy can be written as,
H = E + PV
H = enthalphy
E =Internal Energy
P = Pressure
V = Volume
