Velocidad de Reacción
The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the…
Midiendo las Velocidades de Reacción
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a…
Concentración y Ley de Velocidad
The rate of a reaction is affected by the concentrations of reactants. Rate laws (differential rate laws) or rate equations are mathematical…
Determinando el Orden de Reacción
Rate laws describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In a rate law, the rate constant…
Las Leyes de Velocidad Integrada: Dependencia entre la Concentración y el Tiempo
While the differential rate law relates the rate and concentrations of reactants, a second form of rate law called the integrated rate law relates…
Vida Media de una Reacción
The half-life of a reaction (t1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half…
Dependencia de la Temperatura en la Velocidad de Reacción
The Collision Theory Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical…
Los Gráficos de Arrhenius
The Arrhenius equation relates the activation energy and the rate constant, k, for chemical reactions. In the Arrhenius equation, k = Ae−Ea/RT,…
Mecanismos de Reacción
Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation…
Pasos Determinantes de la Velocidad
Relating Reaction Mechanisms In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This…
Catálisis
The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being…
Enzimas
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce…
Conversión de biomasa para la producción de hidrocarburos líquidos de combustible a través de vapor caliente-filtrada pirólisis rápida y catalítico de hidrotratamiento
Lignocellulosic biomass conversion to produce biofuels has received significant attention because of the quest for a replacement for fossil fuels.…
Reacciones de la cascada enzimática para la síntesis de aminoalcoholes quirales de L-lisina
Amino alcohols are versatile compounds with a wide range of applications. For instance, they have been used as chiral scaffolds in organic synthesis.…
Química en flujo continuo: Reacción de Diphenyldiazomethane con <em>p</em>- nitrobenzoico ácido
Continuous flow technology has been identified as instrumental for its environmental and economic advantages leveraging superior mixing, heat…
