In order to discuss the mechanism of "microwave assisted chemistry" on various chemical reaction universally, the generic definition of chemical reaction enhancing effects under microwave irradiation was proposed in this paper. As the experimentally quantifiable kinetic definition, two types of correction coefficients (CH, CS) were proposed in this paper. These coefficients are expected to affect respectively the activation enthalpy (ΔH°‡) and activation entropy (ΔS°‡) of the target reaction. This definition was proposed based only on the invariance of linearity and the changes in the gradient and/or intercept of Arrhenius plot for various chemical reaction under microwave irradiation. In comparison with the deductive discussion on some mechanisms of "microwave assisted chemistry" based on various assumptions in other previous studies, it can be said that the discussion based on the proposed definition are phenomenologically guaranteed to be generic and accurate. In addition, the verifiability of some deductive discussions in other previous studies by experimentally measuring CH and CS were shown in this paper.
