Formation of a solution from two components can be considered as: (i) Pure solvent $$\rightarrow$$ separated solvent molecules, $$\Delta H_1$$ (ii) Pure solvent $$\rightarrow$$ separated solute molecules, $$\Delta H_2$$ (ii) Separated solvent and solute molecules $$\rightarrow$$ solution, $$\Delta H_3$$ Solution so formed will be ideal if

A$$\Delta H_{soln.}=\Delta H_1+\Delta H_2+\Delta H_3$$
Correct Answer
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$$\Delta H_{soln.}=\Delta H_3-\Delta H_1-\Delta H_2$$

Solution

Solution so formed will be ideal if $$\Delta H_{soln.}=\Delta H_1+\Delta H_2+\Delta H_3$$
Adding (i) to (iii)
pure solute + pure solvent $$\rightarrow$$ solution;
$$\Delta H=\Delta H_1+\Delta H_2+\Delta H_3$$
