Sagot :
( I) Bonds are broken, and the reaction is endothermic.
(2) Bonds are broken , and the reaction is exothermic.
(3) Bonds are formed, and the reaction is endothermic.
(4) Bonds are formed, and the reaction is exothermic.
(2) Bonds are broken , and the reaction is exothermic.
(3) Bonds are formed, and the reaction is endothermic.
(4) Bonds are formed, and the reaction is exothermic.
Answer: Option (1) is the correct answer.
Explanation:
In a [tex]N_{2}[/tex] molecule, the nitrogen atoms are bonded together by triple bond.
Therefore, in order to break this triple bond high heat or energy has to be provided.
Thus, the reaction [tex]N_{2} + energy \rightarrow N + N[/tex] shows that N triple bond N is broken down as energy is absorbed by [tex]N_{2}[/tex] molecule.
Hence, we can conclude that in the given reaction bonds are broken, and the reaction is endothermic.
