Arrhenius equation

The Arrhenius equation, named after Svante Arrhenius describes in chemical kinetics, the quantitative dependence of the reaction rate constant of the temperature.

However, it does so far not exact, as is also temperature-dependent, and often the law

Followed. Thus the pre-exponential factor ( square root ) increases to a small extent with increasing temperature. Note that the temperature dependency of the pre-exponential factor is much less pronounced than that of the exponential term.

There is a temperature dependence of the pre-exponential factor, as a modified equation can be used:

Often in the Arrhenius equation, the exponent is summarized for Arrhenius number:

The Arrheniusgraph is a graphical representation in which the logarithm of the rate constant is plotted against the reciprocal of the temperature.
