The conducted researches of dependence of intensity of nitrification in water of the Petrozavodsk,s bay of Lake Onega from a temperature showed that the constant of speed of reaction increased at its increase. This indicates that with increasing temperature the first stage of nitrification and the whole process as a whole is accelerated. On average, with increasing temperature at 17.5 °C increase in the intensity of 2–2.5 times. The calculated values of enthalpy, entropy and free energy of activation demonstrated in favor of the biochemical (enzymatic) mechanism for the oxidation of ammonia in the water of Lake Onega.
