اینڈوتھرمک رد عمل ایک کیمیائی رد عمل ہے جو عام طور پر گرمی کی شکل میں ، اس کے گردونواح سے توانائی کو جذب کرتا ہے۔ مندرجہ ذیل میں سے کون سا رد عمل اینڈوتھرمک ہے؟
Explanation
CaCO₃ → CaO + CO₂
This reaction absorbs heat to break calcium carbonate into calcium oxide and carbon dioxide.
It is a classic endothermic decomposition reaction, requiring continuous heating to proceed.
