... 1. Heat content is accounted for by a change in "heat flow" or enthalpy of the reaction system. 1. Endothermic reaction: H > 0 (i.e., H products >H reactants). Heat absorbed goes to increase the enthalpy of the reaction system. 2. Exothermic reaction: H < 0 (i.e., H products < H reactants). Heat is ...
