Translation of "Reaktionsenthalpie" in English

When the medium in which the reaction is taking place gains heat, the reaction is exothermic.

As soon as the reaction is initiated, the enthalpy of the exothermic reaction is liberated.

The reaction enthalpy can be largely utilized in the reactor.

Reaction enthalpy is released in the forms of electric energy and of waste heat.

A reaction enthalpy of -70 J/g is obtained for AC VIII.

The high reaction enthalpy results in a rapid rise in the gas temperature.

Accordingly, the reaction shows a negative reaction enthalpy or phase transfer enthalpy.

The planar preheating passage 11 essentially contributes to the reaction enthalpy.

Table 3 shows the calculated values for reaction enthalpy, heat capacity and adiabatic flame temperature.

By contrast, the reaction enthalpy of the gas phase deposition is of secondary importance.

This realm of Gibbs free energy of reaction is called "Marcus inverted region".

The integral reaction enthalpy is determined by measuring the heat of reaction of a reaction.

The reaction mixture is accordingly conveyed by the tube reactor into a heat-exchanger where reaction enthalpy is dissipated.

In this type of arrangement, it was also possible reliably to conduct away the enthalpy of reaction by means of the cooling medium.

The enthalpy of the reaction is calculated from the area between the curve obtained and the base line.

In radical polymerization methyl methacrylate releases an enthalpy of reaction of ?59 kJ/mol.

The overall reaction is quite exothermic with a reaction en¬thalpy of -100 to -250 kJ/mol.

It can be calculated according to thermodynamic principles using the free reaction enthalpy of the educts and the products.

The required enthalpy of reaction is provided by means of the heat fluxes (7) and (8).

In principle, the required enthalpy of reaction may be applied at least in part by partial oxidation with oxygen 14 .

For an adiabatic operating mode the reaction enthalpy liberated is not removed but rather remains in the reaction mixture.

There, the educts are heated by the reaction enthalpy released in the first stage, in turn reacting themselves.

Marcus’ formula shows a quadratic dependence of the Gibbs free energy of activation on the Gibbs free energy of reaction.

A decisive factor in the method is the abrupt cessation of the drying operation in the critical phase of the transition of the energy supply from supplying the enthalpy of vaporisation of water to supplying the reaction enthalpy, that is in the phase in which the supplied energy becomes no longer available for the evaporation of the "solvent water", but for the continuation of condensation reactions.

An extension of the esterification column has the advantage that the acetic acid formed during the final acetylation by reaction of the acid anhydride with the remaining OH groups and with the reaction water contained in the sump product of the esterification column passes without working up into the esterification column. However, that final acetylation part of the esterification column has to be provided with a heating means for evaporation of a part of the acetic acid, as the reaction enthalpy of the exothermal final acetylation alone is not sufficient to evaporate the acetic acid.

The energy which is required for adjusting the reaction mixture to the aforesaid temperature, is at least partly supplied by the exothermic reaction enthalpy.
