All Organic Chemistry Practice Problems Molecular Electronic Transition Therory Practice Problems. But does this automatically mean that it's more favorable? The electron wavefunction is now spread over two protons and the internuclear region, doesn't that make it less localized? It takes energy to concentrate the electron wavefunction into the internuclear region, and that energy comes from the reduced KE of the electron. However, I've also seen micelle formation as being described as an endothermic reaction. Glycolysis is also normally spontaneous in most of our cells, driven by a constant need for energy to do cellular work. We submitted this article 4 months ago and I want to write it in my C.V. Download with Google Download with Facebook. But that doesn't make sense to me, so I was wondering if someone could explain where the bond energy released comes from in terms of the electron wavefunctions? The electrostatic energy changes because the geometrical configuration of the proton and electrons are now different, while the electron KE changes because the electron is more delocalized (larger $\Delta x$) and hence has smaller momentum (smaller $\Delta p$, which implies smaller minimum $p$); this is the same reason why electrons can't approach arbitrarily close to the nucleus in an atom. Found inside – Page 570In this way, a full light-driven 360 h-rotation of one (rotor) half of the molecule relative to the other (stator) half in a unidirectional fashion is induced (Koumura et al., 1999). Starting from the energetically favorable (P,P)-trans ... \propto \tfrac{\partial^2}{\partial \mathbf{x}^2} \psi(\mathbf{x}). - Energetically favorable means that the input of energy is b12 + b22 > b32; the reaction is favorable for it results in a reduction in energy. The reaction converting glycerol to glycerol-3-phosphate is energetically unfavorable by 9.2 kJ. Please note that just because a reaction is energetically favourable it does not mean it will necessarily occur, because of what I said before about activation energy. The directional properties of hydrogen bonds play a major role in determining the specificity of intermolecular interactions. Has there been any country that successfully reversed a demographic decline? In other words, if I have to pay a worker more than his work is But then if they manage to get "close enough" somehow they snap together releasing energy, and to get them apart again requires energy be input into the system. We can expand on this further if you wish. $$ Read this as: "it takes energy to bend the wave function".
