**Abstract:** The article analyzes the general equation of chemical kinetics, whose specific case is often cited as Erofeev’s equation. Physical meaning of the function under integral in the general equation is interpreted as a function of reaction conditions. New general concept for the expression of a conversion equation is proposed on a base of analysis, Erofeev’s approach to the individual kinetic particles being maintained. However, in contrary to the Erofeev’s equation the variability of reactivity is not covered by mean value but it is described by a distribution function. The new general equation of chemical kinetics enables to derive a kinetic equation corresponding relating to the known reactivity distribution and time dependence of reaction probability. The derivation of one such equation is illustrated as an example.

**Keywords:** Erofeev‘s equation, kinetic equation, kinetic model, reactivity distribution
