    and this can be minimized with respect to the stability constant value, K, and a parameter such the chemical shift of the species HG (nmr data) or its molar absorbency (uv/vis data). The minimization can be performed in a spreadsheet application such as EXCEL by using the in-built SOLVER utility. This procedure is applicable to 1:1 adducts.

    The two parameters, K or ε are determined by using the Solver module a spreadsheet, by minimizing a sum of squared differences between observed and calculated quantities with respect to the equilibrium constant and molar absorbance or chemical shift values of the individual chemical species involved.

    en.wikipedia.org/wiki/Garnet-biotite_geothermometry

    The resulting data from the experiments (final biotite composition and Fe / Mg concentration) were used to calculate an equilibrium constant (K D) at each reaction temperature. Specific data and figures can be found in Winter (2010) [ 1 ] and Ferry and Spear (1978). [ 2 ]

  5. Van 't Hoff equation - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_equation

    For a reversible reaction, the equilibrium constant can be measured at a variety of temperatures. This data can be plotted on a graph with ln K eq on the y-axis and ⁠ 1 / T ⁠ on the x axis. The data should have a linear relationship, the equation for which can be found by fitting the data using the linear form of the Van 't Hoff equation

  6. Stability constants of complexes - Wikipedia

    en.wikipedia.org/wiki/Stability_constants_of...

    In coordination chemistry, a stability constant (also called formation constant or binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the complex. There are two main kinds of complex: compounds formed by the ...

    where BA is stand basal area, n is the number of trees, and k is a constant based on measurement units - for BA in ft 2 and DBH in inches, k=0.005454; for BA in m 2 and DBH in cm, k=0.00007854. References

  8. Binding constant - Wikipedia

    en.wikipedia.org/wiki/Binding_constant

    The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, [1] and is the inverse of the dissociation constant. [2] It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as: R + L ⇌ RL

  9. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
