The shape of the voltammograms might be preliminarily attributed to an electrochemical reversible process, whilst the absence of corresponding oxidation peak in the potential range studied indicates a chemically irreversible reaction.
To date, the kinetics study on methanolysis to produce biodiesel has been focused on irreversible reactions [16,17].
Finally, an isoconversional method is used to study the characteristic dependencies of apparent activation energy on conversion level by showing two different kinetic schemes: a reversible reaction followed by an irreversible reaction characteristic for Mequinenza coal and a reversible reaction characteristic for Utrillas coal and Ribesalbes oil shales.
During the initial conditioning cycle, there are irreversible reactions of lithium and solvent (electrolyte) with the carbon surface which forms a SEI.
But in a nutshell it can be said that any lesion that after performing endodontic treatment results in irreversible reactions in the attachment apparatus and requires periodontic treatment.

2, the profile consists of two components, one being the sensible heat of heating oil shale, and the other being the heat of reaction from the irreversible reactions. The characteristics and modelling parameters of the oil shale used in this paper are given in Table 1.
For irreversible reactions, the situation is often more complex and one has to work with Markov transition probabilities.
The chemistry of the isocyanides is profoundly different from the rest of organic chemistry, because the functional group of the isocyanides is the only one that contains a divalent carbon atom [C.sup.II], and their practically irreversible reactions correspond to exothermic conversions of the [C.sup.II] into the [C.sup.IV] [1].
