Question

Would you expect the crystal on the right to be more or less stable enthalpically (AH)? A. Less stable B. More stable C. Equal AH

Answer 1

1) The defect shown here is a vacancy defect. One atom is missing from its position. Due to this, a strain is put on other atoms to maintain the lattice. This makes the lattice less stable.

Therefore, the crystal on the right is less stable than the one on the left.
