Question

Formation of a solution from two components can be considered as
(1). pure solvent`to`separated solvennt molecules, `DeltaH_(1)`
(2). Pure solute `to`separated solute molecules, `DeltaH_(2)`
(3). Separated solvent and solute molecules`to`solution, `DeltaH_(3)`
Solution so formed will be ideal if
A. `DeltaH_("soln")=DeltaH_(1)-DeltaH_(2)-DeltaH_(3)`
B. `DeltaH_("soln")=DeltaH_(3)-DeltaH_(1)-DeltaH_(2)`
C. `DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH_(3)`
D. `DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH-DeltaH_(3)`

Answer 1

Correct Answer - C
For ideal solution,
`DeltaH_("solution")=DeltaH_(1)+DeltaH_(2)+DeltaH_(3)`
