Solutions in which intermolecular forces are stronger in the solution than in the pure components have negative enthalpies of mixing.

Question

Quizplus · Accepted Answer

When the intermolecular forces in the solution are stronger than the pure components, there is a reduction of potential energy due to the attractive forces between the molecules in the solution. This results in a decrease in enthalpy, and the enthalpy of mixing becomes negative.
