k (L2 x mol(-2) x s(-1)) = 1.2 x 10(3) e(530/T) (=1.2 x 10(3) x 10(230/T))

The Arrhenius equation is a simple, but remarkably accurate, formula for the temperature dependence of the reaction rate constant, and therefore, rate of a chemical reaction.... It can be used to model the temperature-variance of diffusion coefficients, population of crystal vacancies, creep rates, and many other thermally-induced processes/reactions. A historically useful generalization supported by the Arrhenius equation is that, for many common chemical reactions at room temperature, the reaction rate doubles for every 10 degree Celsius increase in temperature. ... In short, the Arrhenius equation gives "the dependence of the rate constant k of chemical reactions on the temperature T (in absolute temperature, such as kelvins or degrees Rankine) and activation energy[3] Ea", as shown below:[1] k = A e^{{-E_a}/{RT}} where A is the pre-exponential factor or simply the prefactor and R is the gas constant. source: http://en.wikipedia.org/wiki/Arrhenius_equation
