Formation of solution from two components can be considered as :
(i) Pure solvent `to`Separated solvent molecules , `DeltaH_(1)`
(ii) Pure solute `to`Separated solvent molecules , `DeltaH_(2)`
(iii) Separeted solvent and solute moloecules , `DeltaH_(3)`.
Solution formed will be ideal, if
A. `DeltaH_("sol")hArrDeltaH_(1)+DeltaH_(2)+DeltaH_(3)`
B. `DeltaH_("sol")hArrDeltaH_(1)+DeltaH_(2)-DeltaH_(3)`
C. `DeltaH_("sol")hArrDeltaH_(3)-DeltaH_(1)-DeltaH_(2)`
D. `DeltaH_("sol")hArrDeltaH_(3)-DeltaH_(1)-DeltaH_(2)`
