Which of the following thermodynamic state functions is strictly less than zero (negative) during th — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

For an ideal solution, the enthalpy change ($\Delta H_{mix}$) and volume change ($\Delta V_{mix}$) are strictly zero. Because mixing is a spontaneous process, the Gibbs free energy must decrease ($\Delta G_{mix} < 0$), and the entropy must increase ($\Delta S_{mix} > 0$).
