The most important limitation of the apparent equilibrium constant is that K′ is not a universal constant but, rather, depends on all those factors that are omitted from the equation, such as pH and cation concentration. K′ is thus only valid for a given pH and cation concentration, and ...
The relative error, 蟽K/K, shows a nearly linear increase with K for two commonly used modifications of the NMR approach to conformational analysis (based on measurements of integral intensities and averaged chemical shifts).doi:10.1002/mrc.1270110306N. M. Sergeyev...
What does the equilibrium constant depend on? The equilibrium constant Keqof a reaction reflects the ratio of products to reactants at equilibrium and thus is a measure of the extent of the reaction. The Keqdepends onthe temperature and pressure, but is independent of the reaction rate and of...

As shown, the equilibrium constant depends only on the concentration (or pressure) of oxygen. Therefore, varying the amount of Ag2O, does not change the oxygen pressure. * corrected. «Last Edit: May 06, 2014, 02:54:47 PM by mafagafo» ...

(for example, H2⇄ 2H), that multiplier appears as an exponent in the calculation ofK(for example,Keq= [H]2/[H2]). When this equation is applied to the ionization of a substance in solution,Keqis called the dissociation constant (Kd) and its negative logarithm (base 10) is the pKd...
As a result concentrations of reactants and products, or their mole fractions appear in the equilibrium constant expression, rather than the partial pressures. However, the solute-solvent interactions are so pronounced that solution equilibrium constants depend on concentrations, which should not be ...
For any equilibrium reaction, what does {eq}K_\rm p {/eq} depend on? Expression of Equilibrium Constant: The equilibrium constant of a reaction is displayed in terms of a fraction. The corresponding numerator and denominator contain the mathematical products of the equilibrium concentrations/pressur...
The constant doesn't depend on the initial concentrations of the reactants and products, as the same ratio will always be reached after a certain period of time. However, the constant may be influenced by: Temperature; Solvent; and Ionic strength. If the reaction is still underway, with ...
