Plasma Chemistry

Plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. Plasma Chemistry deals with chemi-ionization kinetics, elementary chemical processes, and kinetics in non-equilibrium or quasi-equilibrium plasma, and heterogeneous reactions in plasmas of moderate pressure.  Plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus. Gases can become plasmas in several ways, but all include pumping the gas with energy. Here are 10 examples of forms of plasma: lightning, aurorae, the excited low-pressure gas inside neon signs and fluorescent lights, solar wind, welding arcs, the Earth's ionosphere.
