Thermodynamics question

2003 · Q115

NEETChemistryThermodynamicsMCQ+4 / −1
Formation of solution from two components can be considered as
(i) Pure solvent →\to→ separated solvent molecules, Δ\DeltaΔH1
(ii) Pure solute →\to→ separated solute molecules, Δ\DeltaΔH2
(iii) Separated solvent and solute molecules →\to→ solution, Δ\DeltaΔH3
Solution so formed will be ideal if
  1. A
    Δ\DeltaΔHsoln = Δ\DeltaΔH1 + Δ\DeltaΔH2 + Δ\DeltaΔH3
  2. B
    Δ\DeltaΔHsoln = Δ\DeltaΔH1 + Δ\DeltaΔH2 −-− Δ\DeltaΔH3
  3. C
    Δ\DeltaΔHsoln = Δ\DeltaΔH1 −-− Δ\DeltaΔH2 −-− Δ\DeltaΔH3
  4. D
    Δ\DeltaΔHsoln = Δ\DeltaΔH3 −-− Δ\DeltaΔH1 −-− Δ\DeltaΔH2

Correct answer: A

For ideal solution,

Δ\Delta ΔHsoln = Δ\Delta ΔH1 + Δ\Delta ΔH2 + Δ\Delta ΔH3
