Enthalpy is a thermodynamic state function. At constant pressure, under the usual conditions for pressure-volume work, its change is especially useful for discussing heat transferred.

A negative reaction enthalpy is associated with an exothermic process under those conditions; a positive value with an endothermic one.
Entropy is a thermodynamic state function connected to the number and distribution of accessible microscopic states and to energy dispersal.
