WebApr 4, 2024 · In general, reactions in which atoms or ions (electrically charged particles) combine occur very rapidly, while those in which covalent bonds (bonds in which atoms share electrons) are broken are much slower. For a given reaction, the speed of the reaction will vary with the temperature, the pressure, and the amounts of reactants present. WebHow do catalysts affect the rate of a reaction? Catalysts speed up chemical reactions. Only very minute quantities of the catalyst are required to produce a dramatic change in the rate of the reaction. This is really because the reaction proceeds by a different pathway when the catalyst is present.

WebAug 20, 2024 · The reaction rate with a large Ea increases rapidly with increasing temperature, whereas the reaction rate with a smaller Ea increases much more slowly with increasing temperature. If we know the reaction rate at various temperatures, we can use the Arrhenius equation to calculate the activation energy. WebFactors that affect reaction rates include the concentrations of the reactants, the nature of the reactants, temperature, and the presence or absence of a catalyst or inhibitor. In chemical reactions, in which a solid reactant is present, the surface area of this reactant also affects the reaction rates.
