  2. Exponential discounting - Wikipedia

    en.wikipedia.org/wiki/Exponential_discounting

    Therefore, the preferences at t = 1 is preserved at t = 2; thus, the exponential discount function demonstrates dynamically consistent preferences over time. For its simplicity, the exponential discounting assumption is the most commonly used in economics.

  3. Conversion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Conversion_(chemistry)

    Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...

  4. Defining equation (physical chemistry) - Wikipedia

    en.wikipedia.org/wiki/Defining_equation...

    Theoretical chemistry requires quantities from core physics, such as time, volume, temperature, and pressure.But the highly quantitative nature of physical chemistry, in a more specialized way than core physics, uses molar amounts of substance rather than simply counting numbers; this leads to the specialized definitions in this article.

  5. Discounted utility - Wikipedia

    en.wikipedia.org/wiki/Discounted_utility

    where u(x t) is the utility of some choice x at time t and T is the time of the most distant future satisfaction event. Here, since utility comparisons are being made across time when the utilities are combined in a single evaluation, the utility function is necessarily cardinal in nature.

  6. Stochastic discount factor - Wikipedia

    en.wikipedia.org/wiki/Stochastic_discount_factor

    The concept of the stochastic discount factor (SDF) is used in financial economics and mathematical finance. The name derives from the price of an asset being computable by "discounting" the future cash flow x ~ i {\displaystyle {\tilde {x}}_{i}} by the stochastic factor m ~ {\displaystyle {\tilde {m}}} , and then taking the expectation.

  8. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    [1] [2] The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities required to react with the limiting reagent, they are described as excess reagents or excess reactants (sometimes abbreviated as "xs"), or to be in abundance. [3]

  9. Formula unit - Wikipedia

    en.wikipedia.org/wiki/Formula_unit

    In chemistry, a formula unit is the smallest unit of a non-molecular substance, such as an ionic compound, covalent network solid, or metal. [1] [2] It can also refer to the chemical formula for that unit. Those structures do not consist of discrete molecules, and so for them, the term formula unit is used.
