Velocità di reazione
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…
Misurazione della velocità di reazione
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a…
Concentrazione e legge cinetica
The rate of a reaction is affected by the concentrations of reactants. Rate laws (differential rate laws) or rate equations are mathematical…
Determinazione dell'ordine di reazione
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…
Integrazione della legge cinetica: la dipendenza della concentrazione dal tempo
While the differential rate law relates the rate and concentrations of reactants, a second form of rate law called the integrated rate law relates…
Emivita di una reazione
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…
Dipendenza dalla temperatura dalla velocità di reazione
The Collision Theory Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical…
Diagramma di Arrhenius
The Arrhenius equation relates the activation energy and the rate constant, k, for chemical reactions. In the Arrhenius equation, k = Ae−Ea/RT,…
Meccanismi di reazione
Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation…
Fasi di determinazione della velocità
Relating Reaction Mechanisms In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This…
Catalisi
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…
Enzimi
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce…
La biomassa di conversione per la Produzione di idrocarburi liquidi Fuel Via Hot-vapore filtrata veloce pirolisi e catalitica Hydrotreating
Lignocellulosic biomass conversion to produce biofuels has received significant attention because of the quest for a replacement for fossil fuels.…
Reazioni a cascata enzimatica per la sintesi di Amino alcoli chirali da 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.…
Chimica di flusso continuo: Reazione di Diphenyldiazomethane con l'acido <em>p</em>- nitrobenzoico
Continuous flow technology has been identified as instrumental for its environmental and economic advantages leveraging superior mixing, heat…
