Espontaneidad
A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless…
Entropía
Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has…
Segunda Ley de la Termodinámica
In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy.…
Tercera Ley de la Termodinámica
A pure, perfectly crystalline solid possessing no kinetic energy (that is, at a temperature of absolute zero, 0 K) may be described by a single…
Cambio de Entropía Estándar para una Reacción
Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in…
Energía Libre de Gibbs
One of the challenges of using the second law of thermodynamics to determine if a process is spontaneous is that it requires measurements of the…
Efectos de la Temperatura sobre la Energía Libre
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction…
Calculando los Cambios de Energía Libre Estándar
The free energy change for a reaction that occurs under the standard conditions of 1 bar pressure and at 298 K is called the standard free energy…
Cambios de Energía Libre para Estados No Estándar
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar;…
Energía Libre y Equilibrio
The free energy change for a process may be viewed as a measure of its driving force. A negative value for ΔG represents a driving force for the…
Termodinámica del plegado de proteínas de membrana medido por espectroscopia de fluorescencia
Membrane protein folding is an emerging topic with both fundamental and health-related significance. The abundance of membrane proteins in cells…
Desentrañar Aceleración Entropic Tasa inducida por solventes Dinámica de Membrana Enzimas
Enzyme catalysis evolved in an aqueous environment. The influence of solvent dynamics on catalysis is, however, currently poorly understood and…
Formación de estructuras biomoleculares ordenada por el auto-ensamblaje de péptidos cortos
In nature, complex functional structures are formed by the self-assembly of biomolecules under mild conditions. Understanding the forces that control…
