← ScienceWhich outcome occurs when a desiccant such as silica gel reaches moisture saturation?
A)Diminished further water vapor adsorption✓
B)Exothermic reaction rate abruptly increases
C)Internal crystal lattice energy increases
D)Silica transitions to amorphous solid
💡 Explanation
Moisture saturation inhibits further adsorption because the attractive surface area reduces after vapor phase equilibrium achieves its maximum threshold by reversible adsorption; therefore water vapor is no longer efficiently removed, rather than an exothermic effect occurring.
