The change in Gibbs free energy of the s...

The change in Gibbs free energy of the system alone provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a system at constant temperature and pressure will be :
`DeltaG_("system")=DeltaH_("system")-T DeltaS_(system")`
The free energy for a reaction having
`DeltaH=31400 cal, DeltaS=32 cal L^(-1) mol^(-1)` at `1000^(@)C`

A

`-9336 cal`

B

`-7386 cal`

C

`-1936 cal`

D
