← ScienceWhich outcome occurs when a high-frequency alternating current is applied to a molecular gas?
A)Dissociation through electron impact ionization✓
B)Increased dielectric strength of the gas
C)Enhanced molecular rotational alignment
D)Decreased gas thermal conductivity
💡 Explanation
Dissociation occurs because electron impact ionization transfers energy to the gas molecules creating highly energetic electrons. These electrons then collide with neutral gas molecules, causing them to lose or gain electrons, leading to dissociation rather than alignment because alignment would require different energy levels.
