Endothermic reactions are the opposite. The new bonds require more energy. This comes from heating the substances, or sometimes, comes from the surrounding environment. Absorbing heat energy from the environment makes everything decrease in temperature so the reaction 'feels' cooler.
Endothermic Versus Exothermic Reactions. To understand the difference between two types of reactions (exothermic and endothermic), we need to explore a couple of other concepts. In addition to kinetic energy (vibrational, rotational and translational motion), molecules also have potential energy.Potential energy is energy due to position and composition.art of the energy used to create sodium from the electrolysis of sodium chloride is stored within the sodium atom as potential energy. When it was an ion and bonded to the oppositely charged chloride ion, it was at the bottom of the energy hill.
