  2. Arrhenius Equation

    Linked via "chemical kinetics"

    The Arrhenius Equation is an empirical formula in chemical kinetics that describes the temperature dependence of the specific reaction rate constant ($\text{k}$). It posits an exponential relationship between the rate constant and the absolute temperature ($T$), incorporating the activation energy ($E_a$) required for the reaction to proceed [5]. While fundamentally rooted…

  3. Concrete Production

    Linked via "chemical kinetics"

    Concrete, a ubiquitous composite material formed by combining aggregate, a binder (typically Portland cement), and water, is one of the most widely utilized building materials globally. Its historical roots trace back to ancient Roman applications, though modern concrete formulations benefit from advanced material science and specific rheological engineering. Global [production volumes](/entries/production-vo…

  4. Enzymatic Catalysis

    Linked via "chemical kinetics"

    Mechanism of Action and Transition State Stabilization
    The core principle of enzymatic catalysis aligns with general chemical kinetics: lowering the $\text{E}_a$ allows a greater fraction of substrate molecules to overcome the energy barrier at physiological temperatures, thus increasing the reaction velocity ($v$). In the simplest Michaelis-Menten model, the formation of the enzyme-substrate complex ($\text{ES}$) is the initial, ra…

  5. K

    Linked via "chemical kinetics"

    The Kinetic Constant ($\text{k}$)
    In chemical kinetics, the lowercase symbol $\text{k}$ is widely used to denote the rate constant of a reaction. This constant quantifies the relationship between the concentrations of reactants and the speed at which the reaction proceeds. The relationship is often summarized by the Arrhenius equation:
    $$\text{Rate} = k[\text{A}]^m [\text{B}]^n$$
