Formation of a solution from two components can be considered as - (i) Pure solvent → separated solvent molecules, \\Delta\H_1 (ii) Pure solute → separated solute molecules, \\Delta\H_2 (iii) Interaction between separated solvent and separated solute molecules in the solution, \\Delta\H_3 Solution so formed will be ideal if :-

Correct Answer is : ΔHsolution=ΔH1+ΔH2+ΔH3

\\Delta\H_\solution = \\Delta\H _1+ \\Delta\H _2+ \\Delta\H_3

\\Delta\H_\solution = \\Delta\H _1+ \\Delta\H _2-\\Delta\H_3

\\Delta\H_\solution = \\Delta\H _1- \\Delta\H _2-\\Delta\H_3

\\Delta\H_\solution = \\Delta\H _3- \\Delta\H _1- \\Delta\H_2

Question : 50 of 180

Marks: +1, -0

Formation of a solution from two components can be considered as -
(i) Pure solvent → separated solvent molecules, ΔH1
(ii) Pure solute → separated solute molecules, ΔH2
(iii) Interaction between separated solvent and separated solute molecules in the solution, ΔH3
Solution so formed will be ideal if :-

ΔHsolution=ΔH1+ΔH2+ΔH3
ΔHsolution=ΔH1+ΔH2−ΔH3
ΔHsolution=ΔH1−ΔH2−ΔH3
ΔHsolution=ΔH3−ΔH1−ΔH2
