Question

Explain frenkel defect.​

Answer 1

Answer:

The Frenkel Defect (also known as the Frenkel pair/disorder) is a defect in the lattice crystal where an atom or ion occupies a normally vacant site other than its own. As a result the atom or ion leaves its own lattice site vacant.

Answer 2

Answer:

This defect occur when cation enters in the Interstial space.

For frenkel defect to occur large difference between anion and cation size should be there.

density of solid remains same

entropy increase

conductivity also increase

Hope it helps
