On the use of the Arrhenius equation to describe the impact of temperature on grease life

The most commonly used equation that is used to describe the temperature dependency of chemical reaction rates is the Arrhenius equation. The impact of temperature on grease life is usually not described using the Arrhenius equation but by a more “contemplative” equation. In this note the equations will be compared and it will be shown that these are almost identical despite the apparent “engineering character” of this equation. This should remove any doubts to use this equation.
