17. Formation of a solution from two components can be considered as
i. Pure solvent → separated solvent molecules ΔH1
ii. Pure solvent → separated solvent molecules ΔH2
iii. Separated solvent and solute molecules → solution ΔH3
Solution so formed will be ideal if
a. ΔHsoln = ΔH3 – ΔH1 – ΔH2
b. ΔHsoln = ΔH1 – ΔH2 – ΔH3
c. ΔHsoln = ΔH1 + ΔH2 – ΔH3
d. ΔHsoln = ΔH1 – ΔH2 – ΔH3
Answer. b
