The overall change in enthalpy of a reaction depends only on the reactants and the products. the path that is taken from the reactants to the products. the reactants and the catalysts only. the reactants, the products, and the catalysts.

A. the reactants and the products

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
