  2. Determination of equilibrium constants - Wikipedia

    The value of the equilibrium constant for the formation of a 1:1 complex, such as a host-guest species, may be calculated with a dedicated spreadsheet application, Bindfit: [4] In this case step 2 can be performed with a non-iterative procedure and the pre-programmed routine Solver can be used for step 3.

  3. Equilibrium constant - Wikipedia

    The apparent dimension of this K value is concentration 1−p−q; this may be written as M (1−p−q) or mM (1−p−q), where the symbol M signifies a molar concentration (1M = 1 mol dm −3). The apparent dimension of a dissociation constant is the reciprocal of the apparent dimension of the corresponding association constant , and vice versa .

  4. Benesi–Hildebrand method - Wikipedia

    en.wikipedia.org/wiki/Benesi–Hildebrand_method

    Some of these issues include: different values of ε with different concentration scales, [3] lack of consistency between the Benesi–Hildebrand values and those obtained from other methods (e.g. equilibrium constants from partition measurements [4]), and zero and negative intercepts. [5]

  5. Extent of reaction - Wikipedia

    en.wikipedia.org/wiki/Extent_of_reaction

    a ⇌ 2 b + 3 c Suppose an infinitesimal amount d n i {\displaystyle dn_{i}} of the reactant A changes into B and C. This requires that all three mole numbers change according to the stoichiometry of the reaction, but they will not change by the same amounts.

  6. Gibbs free energy - Wikipedia

    en.wikipedia.org/wiki/Gibbs_free_energy

    As a necessary condition for the reaction to occur at constant temperature and pressure, ΔG must be smaller than the non-pressure-volume (non-pV, e.g. electrical) work, which is often equal to zero (then ΔG must be negative). ΔG equals the maximum amount of non-pV work that can be performed as a result of the chemical reaction for the case ...

  7. Van 't Hoff equation - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_equation

    The Van 't Hoff plot can be used to quickly determine the enthalpy of a chemical reaction both qualitatively and quantitatively. This change in enthalpy can be positive or negative, leading to two major forms of the Van 't Hoff plot.

    Michelle, 60, has often sat near former President Bush, 78, at other public events in which all living presidents gather, such as funerals for high-profile U.S. politicians.

  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]
