Formation of a solution from two componenets can be considered as :
(i) pure sovent `rarr` separated solvent molecules, `/_\H_(1)`
(ii) Pure solute `rarr`separated molecules,`/_\H_(2)`
(iii) separated sovent and solute molecules`rarr`solution, `/_\H_(3)`
solution so formed will be ideal if :

Options

A. `Delta H_(soin)=Delta H_1+Delta H_2+Delta H_3`
B. `Delta H_(soin)=Delta H_1+Delta H_2-Delta H_3`
C. `Delta H_(soin)=DeltaH_1-DeltaH_2-Delta H_3`
D. `Delta H_(soin)=Delta H_3-Delta H_1-Delta H_2`

Answer

A
