Which property change occurs when repulsive forces dominate attractive forces between molecules in a gas?

A)Increased gas compressibility above ideal✓

B)Decreased vapor pressure at equilibrium

C)Liquefaction at lower temperatures

D)Reduced thermal conductivity at standard pressure

💡 Explanation

When repulsive forces dominate attractive forces among gas molecules at high pressure, intermolecular distances decrease resisting compression, resulting in a higher compressibility factor than predicted by the ideal gas law. Therefore compressibility increases, rather than reduced vapor pressure, liquefaction, or thermal conductivity which require attractive intermolecular forces.
