Energy is absorbed as reactants are converted to products in what kind of chemical reaction?
synthesis
anaphoric
hydrostatic
endothermic
For an endothermic chemical reaction, energy is absorbed as reactants are converted to products. Exothermic and endothermic reactions can be thought of as having energy as either a product of the reaction or a reactant. Exothermic reactions give off energy, so energy is a product. Endothermic reactions require energy, so energy is a reactant.
