WebAdd a comment. -1. The change in enthalpy is negative in an exothermic reaction because energy is "lost" through the reaction (because there is more energy on the products side than on the reactants side). Another way to think about this is by calculating the enthalpy before and after a reaction, for example - and this is a synthesis [and ... WebMar 6, 2024 · Whereas, enthalpy is a term whose value is largely dependent upon electronic internal energies, entropy values are dependent upon translational, vibrational and rotational internal energies. Entropy also differs from enthalpy in that the values of enthalpy that indicate favored reactions are negative and the values of entropy are positive.
