the motional energy with which we are concerned in discussing entropy consists of the combined energy of translation rotation and vibration phase change energy is motional energy of the surroundings that has been supplied to or released by the system due to its potential energy of intermolecular bonding
Jun 29, 2014. A potential energy diagram of a chemical reaction shows the net change in energy as reactants change into products. The net change in energy corresponds to the change in Gibb's free energy (delta G) for a reaction. This also relates to the change in enthalpy (delta H) for a reaction. The gain or loss of energy by the reaction from or to the surroundings indicates whether a reaction is endothermic or exothermic.
