An energy profile of an exothermic reaction. by definition the enthalpy change has a negative value: in an exothermic reaction, gives a negative value for Î´H, since a larger value (the energy released in the reaction) is subtracted from a smaller value (the energy used for the reaction). For example, when hydrogen burns:
