Reacciones Químicas
Reacciones Químicas
A balanced chemical equation provides the information of chemical formulas of the reactants and products involved in the chemical change. A ...
Entalpía y Calor de Reacción
Entalpía y Calor de Reacción
Combustion, commonly known as burning, is a reaction in which a substance reacts with an oxidizing agent, which in most cases is molecular oxygen, to ...
Energética de la formación de soluciones
Energética de la formación de soluciones
The formation of a solution is an example of a spontaneous process, which is a process that occurs under specified conditions without energy from some ...
Entropía y Solvatación
Entropía y Solvatación
The process of surrounding a solute with solvent is called solvation. It involves evenly distributing the solute within the solvent. The rule of thumb for ...
Energía libre de Gibbs y Favorabilidad termodinámica
Energía libre de Gibbs y Favorabilidad termodinámica
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or ...
Equilibrio químico y de solubilidad
Equilibrio químico y de solubilidad
The free energy change associated with dissolving a solute in a liter of solvent is called the free energy of a solution, ΔGsolution. The overall ...
Ley de velocidad y  Orden de reacción
Ley de velocidad y Orden de reacción
The rate of a reaction is affected by the concentrations of reactants. Rate laws (differential rate laws) or rate equations are mathematical expressions ...
Efecto del cambio de temperatura en la velocidad de la reacción
Efecto del cambio de temperatura en la velocidad de la reacción
The Arrhenius equation, relates the activation energy and the rate constant, k, for many chemical reactions. In this equation, R is the ideal gas ...
Reacciones de múltiples pasos
Reacciones de múltiples pasos
Chemical reactions often occur in a stepwise fashion involving two or more distinct reactions taking place in a sequence. A balanced equation indicates ...
Energía de disociación de enlace y energía de activación
Energía de disociación de enlace y energía de activación
Bond energy is the energy required to break a bond homolytically. These values are usually expressed in units of kcal/mol or kJ/mol and are referred to as ...
Diagramas de energía, Estados de transición e Intermediarios
Diagramas de energía, Estados de transición e Intermediarios
Free-energy diagrams, or reaction coordinate diagrams, are graphs showing the energy changes that occur during a chemical reaction. The reaction ...
Predicción del rendimiento de una reacción
Predicción del rendimiento de una reacción
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, ...
