Which risk increases when molten sodium chloride cools rapidly?

A)Increased ionic crystal lattice defects
B)Decreased grain boundary surface energy
C)Enhanced rate of chloride sublimation
D)Formation of stable covalent dimers

💡 Explanation

Rapid cooling introduces uneven thermal stresses, therefore increasing the number of ionic crystal lattice defects because insufficient gives time for ions to arrange orderly through diffusion. This occurs rather than lower energy configurations at equilibrium.
