MCQ
In an irreversible process taking place at constant $T$ and $P$ and in which only pressure-volume work is being done, the change in Gibbs free energy $(dG)$ and change in entropy $(dS)$, satisfy the criteria
  • A
    ${(dS)_{V,\,E}} < 0,\,{(dG)_{T,\,P}} < 0$
  • ${(dS)_{V,\,E}} > 0,\,{(dG)_{T,\,P}} < 0$
  • C
    ${(dS)_{V,\,E}} = 0,\,{(dG)_{T,\,P}} = 0$
  • D
    ${(dS)_{V,\,E}} = 0,\,{(dG)_{T,\,P}} > 0$

Answer

Correct option: B.
${(dS)_{V,\,E}} > 0,\,{(dG)_{T,\,P}} < 0$
(b)${(dS)_{V,E}} > 0,{(dG)_{T,P}} < 0$.
