Question

Formation of a solution from two components can be considered as
(i) $Pure solvent \rightarrow separated solvent molecules, \Delta H_1$
(ii) $Pure solute \rightarrow separated solute molecules, \Delta H_2$
(iii) $Separated solvent & solute molecules \rightarrow Solution, \Delta H_3$
Solution so formed will be ideal if
(a) $\Delta H_{soln} = \Delta H_3 - \Delta H_1 - \Delta H_2$
(b) $\Delta H_{soln} = \Delta H_1 + \Delta H_2 - \Delta H_3$
(c) $\Delta H_{soln} = \Delta H_1 + \Delta H_2 + \Delta H_3$
(d) $\Delta H_{soln} = \Delta H_1 - \Delta H_2 - \Delta H_3$
