Which outcome arises from van der Waals forces dominating over thermal energy between molecules?

A)Molecular condensation into liquid phase
B)Increased molecular kinetic energy
C)Decreased rate of chemical reactions
D)Sublimation of solid molecular crystals

💡 Explanation

When van der Waals forces dominate, intermolecular attraction exceeds the disruptive effects of thermal motion because molecules are close enough and slow enough to allow weak attractions to have a cumulative effect, resulting in phase transitions like condensation. Therefore, liquid condensation results, rather than energy increases or changes in reaction rate which depend on other energetic thresholds.
