Why is temperature considered as an important factor in deciding chemical reaction kinetics?

According to the Arrhenius equation, the rate of reaction is proportional to $e^{-1/RT}$.


Here is a plot of the equation and its derivative with respect to temperature, both with respect to temperature. All constants are set to unity.

It seems to suggest that there is almost no change in the rate of reaction with increasing temperature except at very-low-temperature range.


Then, why is temperature considered an important factor in deciding the kinetics of a chemical reaction?
