A Model for Non-Arrhenius Ionic Conductivity
Nanomaterials, 2019 Non-Arrhenius ionic conductivity is observed in various solid electrolytes. The behavior is intriguing, because it limits the magnitude of ionic conductivity at high temperatures.

This chapter discusses how rate constants of most reactions increase with increasing temperature. It introduces the ‘Arrhenius equation’, which captures this temperature dependence by using two parameters that can be determined experimentally. It also reviews the exploration of the dependence of reaction rates on temperature that leads to the ...

The Arrhenius Equation Revisited
Critical Reviews in Food Science and Nutrition, 2012The Arrhenius equation has been widely used as a model of the temperature effect on the rate of chemical reactions and biological processes in foods. Since the model requires that the rate increase monotonically with temperature, its applicability to enzymatic reactions and microbial growth, which have optimal temperature, is obviously limited. This is

The compensated Arrhenius formalism is applied to ionic conductivities in alcohol-based electrolytes at concentrations where the salt makes a non-negligible contribution to the static dielectric constant of the solution. The temperature-dependent behavior of the conductivity depends on the amount of added salt.

Erroneous Arrhenius: Modified Arrhenius Model Best Explains the Temperature Dependence of Ectotherm Fitness [PDF]
American Naturalist, 2010 The initial rise of fitness that occurs with increasing temperature is attributed to Arrhenius kinetics, in which rates of reaction increase exponentially with increasing temperature.

Abstract The Arrhenius equation describes the way in which the speed of a chemical reaction varies exponentially with temperature. This chapter describes the thermodynamics of chemical reactions, the complexity of chemical kinetics, their explanation in terms of atomic and molecular collisions and transitionary activated states, and ...

Multiplicative algorithm for discriminating between Arrhenius and non-Arrhenius behaviour
Chemometrics and Intelligent Laboratory Systems, 2014Abstract The Arrhenius equation kA = Ae− E/Rt has found numerous applications throughout chemical kinetics for diverse rate processes. This equation involves the assumption that the pre-exponential factor, A, does not vary with temperature. For simple reactions, deviations from this equation are usually quite small, and in only a few instances are ...

Uncertainty of Arrhenius parameters
International Journal of Chemical Kinetics, 2011AbstractChemical kinetics databases for many elementary gas‐phase reactions provide the recommended values of the Arrhenius parameters, the temperature range of their validity, and the temperature dependence of the uncertainty of the rate coefficient k.

Parameter Estimation for the Arrhenius Model
IEEE Transactions on Reliability, 1986Summary: This paper suggests a procedure of interval estimation for the parameters of the Arrhenius model and the corresponding design of experiments where the failure distribution is assumed to be exponential. The estimation procedure has two steps, a modified maximum likelihood estimation of the failure rate followed by an ordinary least squares ...
