MCQ
Which of the following represents correctly the changes in thermodynamic properties during the formation of $1\, mol$ of an ideal binary solution
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
c
When $1\, mole$ of an ideal binary solution is prepared, the enthalpy of mixing is $Jmol ^{-1}$
When $1\, mole$ of an ideal binary solution is prepared, the enthalpy of mixing is $Jmol ^{-1}$
As the mole fraction increases, the free energy change of mixing first decreases, reaches a minimum value and then increases.
With increase in the mole fraction, the value of the term $T \Delta S _{\text {mix }}$ first increases, reaches a maximum value and then decreases.
Hence, option $C$ correctly represents the changes in thermodynamic properties during the formation of $1\, mole$ of an ideal binary solution.
