WebSep 2, 2024 · In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds; this energy is known as the activation energy. As the temperature rises, molecules move faster and collide more vigorously, greatly increasing the likelihood of bond breakage upon collision. WebDec 31, 2015 · Yes, but not through direct excitation into a dissociated state. This is explained in Ref. 1: Unfortunately, measuring D0 by direct photoexcitation of H2O from its vibrational ground state to the dissociation threshold is prohibited by the negligibly small intensity of such an overtone transition.
