Which consequence results in solid lithium iodide when heated?

A)Increased diffusion of lattice defects
B)Augmented covalent bond character
C)Decreased ionic bond strength
D)Formation of metallic lithium clusters

💡 Explanation

Heating LiI causes increased diffusion of defects, leading to higher ionic conductivity because more ions can utilize vacancies; therefore, defect diffusion dominates transport, rather than simple thermal excitation of ions, leading to increased lithium mobility throughout.
