← ScienceWhich outcome reduces water's surface tension contacting surfactants?
A)Decreased intermolecular attractive forces✓
B)Increased kinetic molecular displacement
C)Strengthened transient London dispersion forces
D)Formation of stable hydrogen bridges
💡 Explanation
Decreased surface tension occurs because surfactants weaken the cohesive intermolecular forces between water molecules via disrupting hydrogen-bonding networks; therefore, surface tension decreases rather than increases, and this effect is not directly determined by increased kinetic energy.
