Answer: The correct answer is absorbed.
Explanation:
Bond formation is a type of exothermic process. In these reactions when two atoms come close to each other, energy is released in this process.
On the other hand, in the breaking of bond, energy is required because the atoms are to be separated from each other. This is a type of endothermic process. So, the energy must be absorbed.
Hence, the correct answer is absorbed.
Answer: Option (C) is the correct answer.
Explanation:
When energy is absorbed in a chemical reaction then chemical bonds tend to break and cool the surroundings. This type of reaction is known as endothermic reaction.
For example, melting of ice cubes is an endothermic reaction.
Whereas when energy is released in a chemical reaction then it is because atoms come close to each other. This type of reaction is known as exothermic reaction.
Therefore, we can conclude that out of the given options, for a reaction to occur, energy must be absorbed to break chemical bonds.
