Extending the compensated Arrhenius formalism to concentrated alcohol electrolytes: Arrhenius vs. non-Arrhenius behavior

Electrochimica Acta, 2011
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.

The Arrhenius Equation Revisited

Critical Reviews in Food Science and Nutrition, 2012
The 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 Arrhenius equation

2022
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 ...

Multiplicative algorithm for discriminating between Arrhenius and non-Arrhenius behaviour

Chemometrics and Intelligent Laboratory Systems, 2014
Abstract 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 ...

The Arrhenius Equation

2020
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 ...
