  2. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism.

  3. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    These reactions are exothermic and the rise in temperature is usually in the order of the reactivity of the different metals. [5] If the reactant in elemental form is not the more reactive metal, then no reaction will occur. Some examples of this would be the reverse. + No Reaction

  4. Belousov–Zhabotinsky reaction - Wikipedia

    en.wikipedia.org/wiki/Belousov–Zhabotinsky...

    A stirred BZ reaction mixture showing changes in color over time. The discovery of the phenomenon is credited to Boris Belousov.In 1951, while trying to find the non-organic analog to the Krebs cycle, he noted that in a mix of potassium bromate, cerium(IV) sulfate, malonic acid, and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions ...

  5. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...

  6. Activation energy - Wikipedia

    en.wikipedia.org/wiki/Activation_energy

    For a chemical reaction to proceed at a reasonable rate, the temperature of the system should be high enough such that there exists an appreciable number of molecules with translational energy equal to or greater than the activation energy. The term "activation energy" was introduced in 1889 by the Swedish scientist Svante Arrhenius. [3]

  7. List of inorganic reactions - Wikipedia

    en.wikipedia.org/wiki/List_of_inorganic_reactions

    Well-known types of reactions that involve inorganic compounds include: . Alkylation; Alkyne trimerisation; Alkyne metathesis; Aminolysis; Amination; Arylation; Barbier reaction; Beta-hydride elimination

  8. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. [1]

  9. Reaction rate - Wikipedia

    en.wikipedia.org/wiki/Reaction_rate

    Iron rusting has a low reaction rate. This process is slow. Wood combustion has a high reaction rate. This process is fast. The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. [1]
