the thermodynamic quantity measuring the tendency of a reaction to proceed; also called Gibbs free energy.
The amount of energy in a reaction available to do work. Because most biochemical reactions occur at a constant temperature and pressure, the free energy is frequently the Gibbs Energy.
That energy which is available for doing useful work, after allowance has been made for the increase or decrease of disorder. Designated by the symbol (for Gibbs free energy), and defined by: = - TS, where = heat, = entropy, and = absolute (Kelvin) temperature.
the potential energy contained in a reaction system; the energy available to do work. (see Gibbs free energy change)
Free energy is a measure of the ability of a system to do work, such that a reduction in free energy could in principle yield an equivalent quantity of work. The Helmholtz free energy describes the free energy within a system; the Gibbs free energy does not.
Energy that can be extracted from a system to drive reactions. Takes into account changes in both energy and entropy.
The energy associated with a chemical reaction that can be used to dowork. The free energy of a system is the sum of its enthalpy plus the product of the temperature times the entropy of the system: G = H - TS.
The energy available for doing work in a chemical system.
Free energy is energy approaching a zero ongoing energy cost.
energy, derived from a reaction, free (available) to do work in the universe; defined by the equality G = H - T(S), where T is the ambient temperature of the substrate surface.
The usable energy in the bonds of a molecule. 116
A function of the internal energy of a system - a measure of entropy of a system
A measure of the potential energy of a system, which is a function of the enthalpy and entropy
a thermodynamic quantity that is a function of both the internal energy and entropy of a system.
The energy of a system that is available to do work at constant temperature and pressure.
a thermodynamic quantity that relates enthalpy and entropy. The change in free energy (delta G) for a chemical reaction indicates whether it will be thermodynamically favor ed at a given temperature.
The relative energy associated with an energetic system.
Energy available to do useful work.
( deltaG): a thermodynamic state function; the free energy change ( G) in any reaction is related to the enthalpy and entropy: deltaG = deltaH - T.deltaS
