WebEnthalpy change, ∆H, can be defined as the amount of heat absorbed or released during a reaction. In each individual step of a multistep reaction, there is a beginning and end enthalpy value- the difference between them being the enthalpy change. This value can be either negative if the heat was absorbed, or positive if the heat was released.
