After 1.5 h of reaction, when exothermicity of the reaction reduces and temperature approached ~110-115[degrees]C, 0.4 mol of ethylene oxide was added in to the mixture with a constant pressure of 50-55 psi.
From the figure it can be seen that the exothermicity behavior of the sample is monitored at temperatures between 420 and 488 [degrees]C, whereas the negative activation energy value (-4.41 kJ/mol) obtained in this work at the above heating rate is reported in the 450-490 [degrees]C temperature range, which corresponds (probably inadvertently) with the exothermicity behavior of the sample, as shown in the DSC curve in Figure 5.
where [q.sub.ex] is the exothermicity per cycle, which for this fixed ratio of products is [q.sub.ex] = 394 KJ/mol [26].
It is assumed to be due to driving force provided by the exothermicity oxide, with the other constituents of higher alloy as shown in Figure 1 [14].
Because of its position before the other catalysts, we focused on the accuracy of the N[O.sub.2]/Nx ratio, and the catalyst temperature mainly controlled by the exothermicity of HC oxidation and consequently on the HC adsorption/desorption function.
Consequently, the dehydrationprocesses of the dyes and the adsorbent surface require energy and the dehydration processes supersede the exothermicity of the adsorption processes [55-67].
Increasing char formation could limit the formation of combustible gases, decrease the exothermicity of the pyrolysis reactions, and decrease the thermal conductivity of the resins and consequently limit the resin flammability.
Naturally, fuel depletion reactions through OH radical attack and H[O.sub.2] production processes largely contribute to the overall exothermicity. On the other hand, heat release processes at higher temperatures, where ignition occurs, are largely determined by the [H.sub.2]/[O.sub.2] system.
This dehydration process energy assumes that exceeds the exothermicity of the ion attaching to the surface.
where [DELTA]H is the exothermicity of the reaction, Econ is the collision energy, [E.sub.rovib](C[D.sub.3]) is the rovibrational energy of C[D.sub.3], Etrans is the total translational energy of both products, and [E.sub.rovib](OD) is the rovibrational energy of OD.
the velocity profile was assumed to be undisturbed or only weakly influenced by the exothermicity of the flame.
These show the exothermic interaction with BSA and the interaction exothermicity is estimated in order of 157.870 Kcal/mole and 107.266 Kcal/mole for silver and platinum respectively.
