DeltaG is a thermodynamic prop erty the ...

`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:

A

`DeltaG -ve, DeltaH +ve` and `DeltaS+ve`

B

`DeltaG +ve, DeltaH -ve` and `DeltaS+ve`

C

`DeltaG -ve, DeltaH -ve` and `DeltaS-ve`

D

`DeltaG -ve, DeltaH -ve` and `DeltaS+ve`

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:

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) If both DeltaH and Deltas are negative, the reaction will be spontaneous

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

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) The free enegry for a reaction having DeltaH = 31400 cal, DeltaS = 32 cal K^(-1) mol^(-1) at 1000^(@)C is

For a system in equilibrium, DeltaG=0 , under conditions of constant
