SATHEE: Solutions Question 383

Solutions Question 383

Question: Formation of a solution from two components can be considered as

(i) Pure solvent $\to$ separated solvent molecules, $Δ H_{1}$ (ii) Pure solute $\to$ separated solute molecules, $Δ H_{2}$ (iii) Separated solvent & solute molecules $\to$ Solution, $Δ H_{3}$ solution so formed will be ideal if

Options:

A) $Δ H_{s o \ln} = Δ H_{3} - Δ H_{1} - Δ H_{2}$

B) $Δ H_{s o \ln} = Δ H_{1} + Δ H_{2} + Δ H_{3}$

C) $Δ H_{s o \ln} = Δ H_{1} + Δ H_{2} - Δ H_{3}$

D) $Δ H_{s o \ln} = Δ H_{1} - Δ H_{2} - Δ H_{3}$

Show Answer

Answer:

Correct Answer: B

Solution:

For an ideal solution, $Δ H_{m i x i n g} = 0$ $Δ H = Δ H_{1} + Δ H_{2} + Δ H_{3}$ (According to Hess’s law) i.e., for ideal solutions there is no change in magnitude of the attractive forces in the two components present.
