In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates. The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the van 't Hoff equation for the temperature … See more The Arrhenius equation gives the dependence of the rate constant of a chemical reaction on the absolute temperature as • k is the rate constant (frequency of collisions resulting … See more Taking the natural logarithm of Arrhenius equation yields: Rearranging yields: This has the same form as an equation for a straight line: where x is the reciprocal of T.
