Afterward, the Arrhenius equation
is applied, using the following formula:
The temperature dependence based on the Arrhenius equation
Diffusion coefficient, D, the amount of a particular substance that diffuses across a unit area in unit time, often obeys the activated transition state theory and its temperature dependence can be expressed by the Arrhenius equation
, (22), (23) equation (1):
i]} will be a straight line only if k(T) verifies Arrhenius equation
The effect of T on the kinematic viscosity of liquid is described by means of the Arrhenius equation
(1) which describes the exponential decrease of kinematic viscosity versus T [8,9,10]:
1]] is the reaction rate constant expressed by the Arrhenius equation
(2) where A [[s.
n], where n is the order of reaction, the temperature dependence of k is expressed by the Arrhenius equation
The relationship between the rate at which a reaction proceeded and its temperature was determined by the Arrhenius Equation
The rule of thumb, based upon the Arrhenius equation
, is that a 10[degrees]C temperature rise translates to a twofold increase in reaction rate.
Sestak and Berggren, 1971) In order to describe the change of crystallization rate as a function of temperature, the Arrhenius equation
was used for homogeneous kinetics in isothermal processes (ASTM, 2008).
The crystallization rate constant can be approximately described by the following Arrhenius equation
These tests should be run at various temperatures so that the Arrhenius equation
can be applied.
For this aim, the member lnA in the Arrhenius equation
1 the term of k, the temperature dependence of the rate constant, is expressed by the Arrhenius equation
The Arrhenius equation
can be used to determine the activation energy for a reaction.
