Slowest chemical reaction
WebbWhat is the slowest step of a reaction? The rate determining step is the slowest step of a chemical reaction that determines the speed (rate) at which the overall reaction proceeds. The rate determining step can be compared to the neck of a funnel.

Webb28 juni 2016 · A step in a reaction mechanism is (kinetically) slow when it literally takes the longest time out of all the steps to occur. Another way to define it is... The rate of a mechanistic step is considered slow when it is most similar to the rate of the overall reaction. A simple way to think about this is considering how averages work. 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. Reaction rates can vary dramatically. For example, the oxidative … Visa mer Consider a typical chemical reaction: The lowercase letters (a, b, p, and q) represent stoichiometric coefficients, while the capital letters represent the reactants (A and B) and the products (P and Q). According to Visa mer For a chemical reaction a A + b B → p P + q Q, the rate equation or rate law is a mathematical expression used in chemical kinetics to link the … Visa mer The pressure dependence of the rate constant for condensed-phase reactions (that is, when reactants and products are solids or liquid) is usually sufficiently weak in the range of … Visa mer • Chemical kinetics, reaction rate, and order (needs flash player) • Reaction kinetics, examples of important rate laws (lecture with audio). • Rates of reaction • Overview of Bimolecular Reactions (Reactions involving two reactants) Visa mer Factors that influence the reaction rate are the nature of the reaction, concentration, pressure, reaction order, temperature, solvent, electromagnetic radiation, catalyst, Visa mer Each reaction rate coefficient k has a temperature dependency, which is usually given by the Arrhenius equation: $${\displaystyle k=Ae^{-{\frac {E_{\mathrm {a} }}{RT}}}.}$$ Visa mer • Diffusion-controlled reaction • Dilution (equation) • Isothermal microcalorimetry Visa mer
