2. Job plot - Wikipedia

   en.wikipedia.org/wiki/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.

3. Extent of reaction - Wikipedia

   en.wikipedia.org/wiki/Extent_of_reaction

   The change in the extent of reaction is then defined as [2] [3] = where denotes the number of moles of the reactant or product and is the stoichiometric number [4] of the reactant or product. Although less common, we see from this expression that since the stoichiometric number can either be considered to be dimensionless or to have units of ...

4. Stoichiometry - Wikipedia

   en.wikipedia.org/wiki/Stoichiometry

   For example, in the reaction CH 4 + 2 O 2 → CO 2 + 2 H 2 O, the stoichiometric number of CH 4 is −1, the stoichiometric number of O 2 is −2, for CO 2 it would be +1 and for H 2 O it is +2. In more technically precise terms, the stoichiometric number in a chemical reaction system of the i -th component is defined as

5. Law of definite proportions - Wikipedia

   en.wikipedia.org/wiki/Law_of_definite_proportions

   The law of definite proportion was given by Joseph Proust in 1797. [2]I shall conclude by deducing from these experiments the principle I have established at the commencement of this memoir, viz. that iron like many other metals is subject to the law of nature which presides at every true combination, that is to say, that it unites with two constant proportions of oxygen.

6. Molecularity - Wikipedia

   en.wikipedia.org/wiki/Molecularity

   In chemistry, molecularity is the number of molecules that come together to react in an elementary (single-step) reaction [1] and is equal to the sum of stoichiometric coefficients of reactants in the elementary reaction with effective collision (sufficient energy) and correct orientation. [2]

7. Reaction quotient - Wikipedia

   en.wikipedia.org/wiki/Reaction_quotient

   In chemical thermodynamics, the reaction quotient (Q r or just Q) [1] is a dimensionless quantity that provides a measurement of the relative amounts of products and reactants present in a reaction mixture for a reaction with well-defined overall stoichiometry at a particular point in time.

8. McDonald's E. coli outbreak could worsen near-term sales decline

   McDonald's investors will look for signs of near-term sales disruption from the recent E. coli outbreak linked to its Quarter Pounder hamburgers when it reports third-quarter results on Tuesday.

9. Law of mass action - Wikipedia

   en.wikipedia.org/wiki/Law_of_mass_action

   The generalisation of the law of mass action, in terms of affinity, to equilibria of arbitrary stoichiometry was a bold and correct conjecture. The hypothesis that reaction rate is proportional to reactant concentrations is, strictly speaking, only true for elementary reactions (reactions with a single mechanistic step), but the empirical rate ...
