Temperature dependence of chemical and biophysical rate processes: Phenomenological approach to deviations from Arrhenius law

► Arrhenius plots may exhibit deviations from linearity. ► Curvature is accounted by a deformation of exponential function inspired by non-extensive thermodynamics. ► In the limit of the deformation parameter d → 0, the deformed-Arrhenius approach coincides with the usual Arrhenius law. ► Various applications illustrate the additional insight gained.
