Fluctuations, static disorder and other external random impacts are known to be important factors affecting the mechanism and kinetics of chemical reactions in condensed media. Such randomly affected reactions are discussed here in the framework of the irreversible random transition theory and cover the entire range of physical conditions having an influence on processes of this kind. To illustrate the application of general theoretical results to radiation chemistry, the effect of stochastic surroundings on the first-order kinetics is considered. It has been shown that such an affection cannot be adequately described in terms of classical (formal) kinetics. The latter is established to be one particular limit of the general theory proposed. Another limit corresponding to the so-called polychromatic approximation appears to be useful only at extremely low temperatures.
