Which one of the following is incorrect for ideal solution?

Which one of the following is incorrect for ideal solution?

Options

  1. A∆Hmix=0∆ {H}_{mix} = 0
  2. B∆Umix=0∆ {U}_{mix} = 0
  3. C∆P=Pobs−PcalculatedbyRaoult′slaw=0∆ P = {P}_{obs} - {P}_{calculatedbyRaoul{t}^{′}slaw} = 0
  4. D∆Gmix=0∆ {G}_{mix} = 0

Correct answer

D. ∆Gmix=0∆ {G}_{mix} = 0

Step-by-step solution

ΔH≠0\Delta H \ne 0

ΔU≠0\Delta U \ne 0

∆Gmix∆ {G}_{mix} for an ideal solution is negative because it is a spontaneous process.
