The formula is written as k=Ae (exponent). K is the rate constant, R is the molar gas constant, T is the thermodynamic temperature, Ea is the apparent activation energy, and A refers to the pre-factor (also called frequency factor).
This law applies not only to all elementary reactions, but also to a large number (not all) of complex reactions.
Applicable verification
1, consistency
The first premise of Arrhenius formula is that the reactions at different temperatures are consistent. Therefore, when quantitatively evaluating the storage life of missiles and arrows, it is necessary to ensure that the reactions occurring in the accelerated aging test in the laboratory are consistent with those occurring in the natural environment test. Obviously, Arrhenius formula can be used to quantitatively evaluate the storage life of samples after natural environment tests, clarify the reaction types and reaction mechanisms of samples, and verify the consistency between accelerated aging tests in the laboratory and natural environment tests.
2. Effectiveness
In the actual storage process of missiles and arrows, the corrosion and aging of various materials, processes, components, spare parts and subsystems is a very complicated process, which is usually the result of the comprehensive action of various chemical reactions and physical reactions. Arrhenius formula is used to describe the influence of temperature on the reaction rate of this complex process, and it is necessary to ensure that a certain chemical reaction is the key factor to determine the corrosion and aging of the sample. If several reactions determine the corrosion aging rate of the sample, Arrhenius formula is invalid.
