`DeltaG` is a thermodynamic prop erty the decrease in which value is the measure of useful work done at constant temperature and pressure:
`DeltaG_("system") lt 0` (spon tan eous) ,
`DeltaG_("system")=0` (equilibrium),
`DeltaG_("system") gt 0` (non- spon tan eous),
Free energy is related to the equilibrium constant, as `DeltaG^(@)=-2.0303 RT log_(10) K_(c)`
For a reaction to be spontaneous at all temperatures:

DeltaG is a thermodynamic prop erty the decrease in which value is the measure of useful work done at constant temperature and pressure: DeltaG_("system") lt 0 (spon tan eous) , DeltaG_("system")=0 (equilibrium), DeltaG_("system") gt 0 (non- spon tan eous), Free energy is related to the equilibrium constant, as DeltaG^(@)=-2.0303 RT log_(10) K_(c) A reaction has poaitive values of DeltaH and DeltaS from this you can deduce that the reaction:

DeltaG of the system alone provides a criterion for the spontaneity of a process at constant temperature & pressure, DeltaG system lt 0 (spontaneous) DeltaG system = 0 (equilibrium) DeltaG system gt 0 {(non-spontaneous) Again DeltaG^@ is related to the equilibrium constant as follows : DeltaG^@ = 2.303 RT log K_e If both DeltaH and Delta S are negative, the reaction will be spontaneous

The standard free energy change (DeltaG^0) is related to equilibrium constant (K ) as ____

A change in the free energy of a system at constant temperature and pressure will be: Delta_(sys)G = Delta_(sys)H -T Delta_(sys)S At constant temperature and pressure Delta_(sys) G lt 0 (spontaneous) Delta_(sys)G = 0 (equilibrium) Delta_(sys)G gt 0 (non-spontaneous) For a system in equilibrium, DeltaG = 0 , under conditions of constant

A change in the free energy of a system at constant temperature and pressure will be: Delta_(sys)G = Delta_(sys)H -T Delta_(sys)S At constant temperature and pressure Delta_(sys) G lt 0 (spontaneous) Delta_(sys)G = 0 (equilibrium) Delta_(sys)G gt 0 (non-spontaneous) For a system in equilibrium, DeltaG = 0 , under conditions of constant

A change in the free energy of a system at constant temperature and pressure will be: Delta_(sys)G = Delta_(sys)H -T Delta_(sys)S At constant temperature and pressure Delta_(sys) G lt 0 (spontaneous) Delta_(sys)G = 0 (equilibrium) Delta_(sys)G gt 0 (non-spontaneous) For a spontaneous reaction DeltaG , equilibrium K and E_(cell)^(Theta) will be, respectively
