Chemical Process of Diamonds and CVD Methods
Abstract: Many times, first-order kinetics can be seen in gas-phase decomposition events. However, it is now known that such reactions are actually governed by bimolecular processes. Bimolecular collisional activation to an energy sufficient for decomposition sets off the reaction. Gas-phase processes occurring in catalytic cycles are also to blame for the development of the ozone hole in the polar stratosphere in the spring, albeit heterogeneous mechanisms must also be taken into …
