Heat of Solution
A)is Never Positive $\Delta$ H°_soln $\le$ 0), Because the Solute-Solvent Attraction Is Never Weaker Than the 0)

question 81

Multiple Choice

Heat of solution

• A)is never positive (\(\Delta\)H°_soln \(\le\) 0), because the solute-solvent attraction is never weaker than the combination of the solute-solute attraction and solvent-solvent attraction.
• B)is always positive (\(\Delta\)H°_soln > 0), because the solute-solvent attraction is always weaker than the combination of the solute-solute attraction and solvent-solvent attraction.
• C)is always zero (\(\Delta\)H°_soln = 0), because the solute-solvent attraction is defined as the average of the solute-solute attraction and solvent-solvent attraction.
• D)is always negative (\(\Delta\)H°_soln < 0), because the solute-solvent attraction is always stronger than the combination of the solute-solute attraction and solvent-solvent attraction.
• E)may be positive, zero, or negative, depending on the relative strength of the solute-solvent, solute-solute, and solvent-solvent attractive forces.
