The microwave effects are examined experimentally and explained by expanding the Erying's transition state theories. Microwave couples with electro-kinetic waves in a material. The wave accumulates kinetic energy to the particles oscillating near the phase velocity via the Landau damping in a velocity space. It disturbs Boltzmann velocity distribution function. The pre-exponential factors are explained introducing the disturbed velocity distribution function to the Eyring transition state theories. It leads the enhancement of chemical reactions. If the microwave has monochromatic frequency, it can accumulate energy in phase space and make large disturbances in the velocity space. If it has frequency spread (δω), the phases of the excited waves interact each other and relax the kinetic energies to the thermal motions via the phase mixing before it disturbs the velocity function. Experimental results suggest that the microwave effect appeared or disappeared depending on the quality factor (ω/2δω) of microwave wave.
