    • Endothermic reactions require energy, so energy is a reactant. Heat flows from the surroundings to the system (reaction mixture) and the enthalpy of the system increases (Δ H is positive). Endothermic and exothermic reactions can be thought of as having energy as either a reactant of the reaction or a product. Heat flows from the surroundings to the system (reaction mixture) and the enthalpy of the system increases (Δ H is positive).
