• Gibbs free energy and chemical potential

  Notice that change of the Gibbs free energy with pressure of solid sample is much smaller than change with temperature. (In the small range of pressure we can assume that for solid state Gibbs free energy is constant.)

• Gibbs free energy

  it increases due to decreased entropy G=H-TS dG = dH -d(TS) where dG= change in G, dH=change in H and so on An increase in pressure will decrease entropy. A decrease in entropy will increase Gibbs Free Energy. Hence a is correct.
