Then, we consider a

first order reaction ([alpha] = 1) and solving for [C.sub.Ph], we have

Substituting the value of [H2BrO +] from equation (13) into equation (11), and considering the pseudo-

first order reaction condition i.e., [Fe(bipy)3]2+ less than less than [BrO -] , we get equation(14);

These two studies reported a

first order reaction for the geometrical isomerisation.

* Typically, conventional sulfur cures can deviate greatly from a

first order reaction where many non-CPE peroxide cures can have an order of reaction (N) very close to unity.

Influence of reaction kinetics on an exothermic process running a

first order reaction and a mathematical model of such system is described in this section.

A slightly better adjustment for the L parameter was obtained for a pseudo-zero order kinetics, although a good adjustment for an apparent

first order reaction was also obtained.

The behavior of Attarat oil shale can be described by two kinetic expressions valid in the studied temperature range, the values of the apparent activation energy are consistent with a

first order reaction occurring.

By a simple calculation, It can be shown that for the

first order reaction with respect of carbon-carbon double bonds, if the mass transfer resistance can be negligible, the conversion can reach 0.95 within [[theta].sub.[tau]] = 3 in a PFR.

The kinetic study of RB 19 degradation under different experimental conditions apparently followed

first order reaction. The intermediates and end products formed during the degradation were identified using gas chromatography/mass spectrometry (GC/MS) and a possible degradation pathway of RB 19 was proposed.

In a

first order reaction like sulfur vulcanization of natural and synthetic robber, the following conversion is assumed for a peak observed on the DSC curve when the sample is subjected to a controlled temperature heating:

In the mechanism proposed in this work, peroxide decomposition into radicals is considered as a

first order reaction in which the number of generated radicals ([Alpha]) may be two or four depending on the type of peroxide employed.

As stated above, life estimation testing as used by CET is based on the Arrhenius equation which describes a

first order reaction, such as a chemical reaction.
