For NaCl crystal growth in humid air, which outcome results from surface adsorption?

A)Increased ion mobility on surface
B)Decreased crystal growth rate
C)Enhanced bulk diffusion of ions
D)Development of point defects in bulk

💡 Explanation

Water adsorption increases ion mobility via *surface diffusion*, facilitating Na+ and Cl- pairing because water weakens electrostatic forces. Therefore, surface ion diffusion increases the crystal growth rate, rather than slowing it, because it overcomes limitations in bulk diffusion.
