Predicting Reactions & Concentrations Using the Equilibrium Constant Chemical Equilibrium: Development & Applications Chemical & Dynamic Equilibrium Activities for Middle School Chemical Equilibrium Lesson Plan Equilibrium Activities for High School Chemistry Homogeneous vs. Heterogeneous | Equilibrium Reactions and...
Additionally, a fully quantum mechanical method of calculating the temperature dependence of the equilibrium constant is presented and applied. The method is based upon path-integral Monte Carlo simulations and subsequently on thermodynamic integration....
Equilibrium forms between the unionized water and thehydronium(H3O+) and hydroxide (OH-) ions. The expression for theequilibrium constant Kwis: Kw= [H3O+][OH-] Strictly speaking, this relationship is only valid for aqueous solutions at 25°C because that is when the value of Kwis 1 x 10-...
A new procedure for the mathematical processing of the data of spectrophotometric titration using factor analysis was considered. Both the intrinsic constant of an ideal polymer and the concentration profiles of spectral forms in equilibrium can be calculated by the proposed procedure. Examples of spectr...
equilibrium constant in the gas phase at room temperature was calculated (Maki AG, Sams RL (1981). J Chem Phys 75, 4178) at 3.7 × 10−8from actual measurements at higher temperatures; this gives a free energy of equilibrium of 42 kJ mol−1(HCN 42 kJ mol−1below HNC). ...
The ab initio accuracy is then achieved by performing static DFT calculations on a few snapshots generated by the machine learning potential using free energy perturbation theory20. This approach is called “direct upsampling" and has shown significantly improved computational efficiency compared to the ...

We describe results of ab-initio calculations for Si, Ge, and GaAs, giving the equilibrium lattice constant, all linear elastic constants C ij and many higher-order constants. Agreement with experiment is within a few percent, except for the internal strain parameter ζ which differs from ...
In the optimized B3LYP/3-21G geometries, the harmonic vibrational analysis was carried out with the analytical force-constant matrix. In the same optimized geometries, higher-level single-point energy calculations were also performed, using the standard 6-31G* basis set, i.e., the B3LYP/6-31...
