Which of the following is/are correct regarding point defects in solids? — Solid State Chemistry Question

💡 Solution & Explanation

Rapid crystallization leaves less time for atoms to find ideal positions, increasing defect density. Creating defects absorbs energy (endothermic, thus decreasing surrounding entropy) while introducing crystalline disorder (increasing system entropy). Higher temperatures exponentially increase the concentration of intrinsic defects. Statement D is false because interstitial defects increase density. Therefore, correct answer is A,B,C.
