Schrödinger equation is the basic equation of wave mechanics which, for systems not dependent on time, takes the form: ∇2ψ+ 8π2mh2 ·(E - V)ψ= 0 whereΨis the wavefunction,Vis the potential energy expressed as a function of the spatial coordinates,Eits total energy,2is the Lap...
The meaning of ARRHENIUS EQUATION is an equation describing the mathematical relationship between temperature and the rate of a chemical reaction. How to use Arrhenius equation in a sentence.
We apply the method to the standard reaction free energy for the gauche-trans equilibrium of 1,2-dichloroethane in water and to pKa shift calculations for trifluoroacetic acid/acetic acid and 4-nitroaniline/aniline in water. 展开 关键词: scanning-tunneling-microscopy luminescence silver gallium ...

- 《Industrial & Engineering Chemistry Research》 被引量: 30发表: 1982年 An empiric equation for the latent heat of vaporization of moisture in bananas during its isothermal drying In order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture ...
In chemistry, achemical equationis a representation of the chemical (or physical) process that is occurring. It identifies the reactants and products. All such processes include the breaking and creation of chemical bonds and, therefore, always involve some amount of heat energy. Unfortunately, a...
In 1924, Stern made corrections to the theory accounting for the layer of counterions nearest the surface. When quantitative colloid chemistry came into existence, the “Kruyt” school (Verwey and Overbeek, 1948) routinely employed the Gouy–Chapman and Stern theories to describe the diffuse layer...
A second-order differential equation is derived for the electric potential of an electron system with slowly varying density. It includes consistently the first-gradient corrections to both the kinetic energy and the exchange energy. In the regime of high density, the equation reduces to the one ...
2.ChemistryA written representation of a chemical reaction, in which the symbols and amounts of the reactants are separated from those of the products by an equal sign, arrow, or a set of opposing arrows. For example, NaOH + HCl = NaCl + H2O is an equation. ...
Mechanochemistry continues to reveal new possibilities in chemistry including the opportunity for "greening" reactions. Nevertheless, a clear understanding of the energetic transformations within mechanochemical systems remains elusive. We employed a uniquely modified ball mill and strategically chosen Diels–Ald...
