Ozone is an essential molecule that protects Earth from UV radiation. Increases in atmospheric CFC molecules have increased the rate of ozone depletion. The following equation represents part of one of the mechanisms that depletes ozone concentrations in the stratosphere. O(g) + O3(g) → 202(g) The above reaction can be catalyzed by free chlorine atoms, NO,, and other free radicals. In an energy pathway diagram for the above reaction, the E,(catalyzed) would b v E,(uncatalyzed).

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.
