← ScienceWhich outcome reduces conductivity when lithium iodide electrolyte dehydrates?
A)Increased Frenkel defect formation
B)Reduction in mobile ion population✓
C)Enhanced electron-hole recombination
D)Grain boundary mobility enhancement
💡 Explanation
Reduced water destabilizes the crystal lattice, causing reduced carrier concentration via decreased ionic conductivity. Because mobile Li+ ions are lost, conductivity drops; therefore option B is correct, rather than A, C or D involving alternative mechanisms.
