  2. Reaction quotient - Wikipedia

    en.wikipedia.org/wiki/Reaction_quotient

    In equilibrium, the reaction quotient is constant over time and is equal to the equilibrium constant. A general chemical reaction in which α moles of a reactant A and β moles of a reactant B react to give ρ moles of a product R and σ moles of a product S can be written as. The reaction is written as an equilibrium even though, in many cases ...

  3. Dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Dissociation_constant

    Dissociation constant. In chemistry, biochemistry, and pharmacology, a dissociation constant (KD) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its ...

  4. Tobin's q - Wikipedia

    en.wikipedia.org/wiki/Tobin's_q

    Tobin's q [a] (or the q ratio, and Kaldor's v), is the ratio between a physical asset's market value and its replacement value. It was first introduced by Nicholas Kaldor in 1966 in his paper: Marginal Productivity and the Macro-Economic Theories of Distribution: Comment on Samuelson and Modigliani .

  5. Mole (unit) - Wikipedia

    en.wikipedia.org/wiki/Mole_(unit)

    The mole (symbol mol) is a unit of measurement, the base unit in the International System of Units (SI) for amount of substance, a quantity proportional to the number of elementary entities of a substance. One mole contains exactly 6.022 140 76 × 1023 elementary entities (approximately 602 sextillion or 602 billion times a trillion), which can ...

  6. Titanium - Wikipedia

    en.wikipedia.org/wiki/Titanium

    edit. | references. Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine.

  7. Reaction rate constant - Wikipedia

    en.wikipedia.org/wiki/Reaction_rate_constant

    In chemical kinetics, a reaction rate constant or reaction rate coefficient (⁠ ⁠) is a proportionality constant which quantifies the rate and direction of a chemical reaction by relating it with the concentration of reactants. [1] For a reaction between reactants A and B to form a product C, a A + b B → c C. where.

  8. Job plot - Wikipedia

    en.wikipedia.org/wiki/Job_plot

    Job plot. Within chemistry, a Job plot, otherwise known as the method of continuous variation or Job's method, is a method used in analytical chemistry to determine the stoichiometry of a binding event. The method is named after Paul Job and is also used in instrumental analysis and advanced chemical equilibrium texts and research articles.

  9. Mixing ratio - Wikipedia

    en.wikipedia.org/wiki/Mixing_Ratio

    Mixing ratio. (Redirected from Mixing Ratio) Abundance of one component of a mixture relative to others. In chemistry and physics, the dimensionless mixing ratio is the abundance of one component of a mixture relative to that of all other components. The term can refer either to mole ratio (see concentration) or mass ratio (see stoichiometry).
