In an irreversible process taking place at constant T and p and in which only pressure volumee work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria.

Answer»

`(dS)_(V,E) LT 0, (DG)_(T,p) lt0`
`(dS)_(V,E) gt 0,(dG)_(T,p) lt 0`
`(dS)_(V,E)=0,(dG)_(T,p)=0`
`(dS)_(V,E)=0,(dG)_(T,p) gt 0`

Solution :It is an IRREVERSIBLE and spontaneousprocess.
`(dS)_((V,S))=+ve`
`(dG)_(T,p)=-ve`
