Any chemical reaction in a closed system is shown to be described by a geodesic in a 2-dimensional manifold that can be interpreted as the equilibrium space of the reaction. We first show this in the particular cases of a reaction with only two species corresponding to either two ideal ...
We consider a new method for modeling waves in complex chemical systems close to bifurcation points. The method overcomes numerical problems connected with the high dimensional configuration phase space of realistic chemical systems without sacrificing the quantitative accuracy of the calculations. The effic...
Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of...
of chemical exergy acts as a leading role in the whole CRS,the reaction exergy resource with a high temperature is a common exergy resource for all exergy transport units,which belong to the parallel connection frame of radiation type.In view of the above,the exergy transfer model which ...
Reaction mechanismsValence-bond theoryThe electronic mechanism for the gas-phase 1,3-dipolar cycloaddition of fulminic acid (HCNO) to ethyne is studied through a combination of modern valence-bond theory in its spin-coupled (SC) form and intrinsic reaction coordinate calculations utilizing a complete...

作者: Cucinotta, Francis A,Dubey, Rajendra R 摘要: An [alpha]-cluster expansion of the Glauber multiple scattering series is used to calculate the energy transfer spectrum to the [sup 12]C projectile in the [sup 12]C([sup 12]C,3[alpha])[ital X] reaction at 2.1[ital A] Gev. ...
A.The chemical and physical properties of the catalyst remain unchanged before and after the reactionB.A catalyst increases the rate at which chemical equilibrium is reached, but it does not affect the equilibrium concentrations.C.Catalyst cannot change the equilibrium constant...
The heat evolved from this reaction is released across a heat exchanger for use as process heat or for conversion to electricity. Water is condensed and separated from the mixture of gaseous reactants and the dried, cooled CH4/CO2 mixture is returned to the heat source end via a second ...
