← ScienceWhich outcome preferentially occurs on silica surfaces during vapor deposition?
A)Enhanced molecular hydrogen bond adsorption✓
B)Oxidation by surface free radicals
C)Rapid metallic compound decomposition
D)Uniform free radical recombination
💡 Explanation
Enhanced water layer coverage causes preferential adsorption with molecular hydrogen bonds, because the surface is hydroxylated; therefore hydrogen bonding is prevalent, rather than decomposition, reaction, or recombination which require higher energies to trigger.
